DLPA2000 is part of the chipset comprising of either DLP2010 (0.2 WVGA) DMD and DLPC3430/DLPC3435 controller or the DLP2010NIR (0.2 WVGA NIR) DMD and DLPC150 controller. The DLPA2000 contains a complete LED driver including high efficiency power convertors. The DLPA2000 can supply up to 750 mA per LED. Integrated high-current switches are included for sequentially selecting R, G, and B LEDs. The DLPA2000 also contains three regulated DC supplies for the DMD reset circuitry: VBIAS, VRST and VOFS, as well as a regulated DC supply of 1.1 V and a load switch for the 1.8 V to support the DLPC3430 or DLPC3435 controller. The DLPA2000 also contains a motor driver which can be used to drive the focus lens motor. The DLPA2000 has a SPI used for setting the configuration. Using SPI, currents can be set independently for each LED with 10-bit resolution. Other features included are the generation of the system reset, power sequencing, input signals for sequentially selecting the active LED, IC self-protections, and an analog MUX for routing analog information to an external ADC. 14 Submit Documentation Feedback Copyright © 2014–2018, Texas Instruments Incorporated Product Folder Links: DLPA2000 DLPA2000 www.ti.com DLPS043B – JUNE 2014 – REVISED FEBRUARY 2018 7.2 Functional Block Diagram VINA From system power REFERENCE SYSTEM V2V5 LDO_V2V5 VREF 2.2µ VLED 1µ UVLO VREF VLED_OVP V6V LDO_V6V 100n LOW_BAT VINL VREF AGND AGND1 A SET_LOW_BAT_USB B AFE_GAIN [1:0] From host CMP_OUT To host AFE_SEL[3:0] AFE PWM_IN MUX SENS1 SENS2 From light sensor From temperature sensor VLED BUCK-BOOST C VINA/3 VLED/3 SW4 SW5 SW6 RLIM_K VREF D L1 From system power 1µ PGNDL 2.2µ L2 VLED 22µ 22µ SW4 SW5 SW6 RGB STROBE DECODER RLIM VINR From system power 10µ VRST 220n 100k SWN REF_VRST SWP RLIM_K RBOT_K E 10µ H CNTR_VRST 220n VBIAS VOFS PGNDR VBIAS VOFS MOTOR DRIVER VINM Full H-Bridge Aout1 Aout2 Full H-Bridge Bout1 Bout2 RLIM From system power G F DMD RESET REGULATORS 220n VINC SWC VCORE BUCK From system power 2.2uH Vout DCDC1 (0.9-1.2V @ 450mA) 10µF PGNDC/PGNDM VCORE LS_IN from any 1.8V-3.3V supply LS_OUT Load Switch to system load 10PF V2V5 PROJ_ON LED_SEL0 LED_SEL1 From host From host From host RESETZ To system 0.1u From host From host From host From host To host VSPI SPI_CSZ SPI_CLK SPI_DIN SPI_DOUT DIGITAL CORE INTZ 5k VIO (depends on DPP requirements) To DPP (optional) SPI DGND A.

These rails are VOFS, VBIAS, and VRST. After pulling the PROJ_ON pin high, the DMD is first initialized followed by a power-up of the VOFS line after a small delay of less than 10 ms followed by VBIAS and VRST with an additional delay of 145 ms. The LED driver and STROBE DECODER circuit can only be enabled after all three rails are enabled. There are two power-down sequences, the normal power-down timing initiated after pulling the PROJ_ON pin low, and a fast power-down mode where if any one of the rails encounters a fault such as an output short, all three rails are discharged simultaneously. The detailed power-up and power-down diagrams are shown in Figure 5 and Figure 6. 5 ms (min) System Power (VINx) 10 ms 25 ms PROJ_ON DMD_EN in register 0x01h V2V5 Stop Regulating VBIAS VBIAS Pad DMD_EN by DPP through SPI write VOFS VRST 10 ms DMD ” 10 ms initialization by DPP •10 ms Stop Regulating VRST 145 ms VCORE LS_OUT (1.8 V) VLED INTZ Startup DPP RESETZ STATE OFF STANDBY ACTIVE1 ACTIVE2 OFF Figure 5.

The NMOS switches are connected to the terminals of the external LED package and turn the currents through the LEDs on and off. Package connections are shown in Figure 7 and Figure 10 and the corresponding switch map is in Table 1. The LED_SEL[1:0] signals typically receive a rotating code switching from RED to GREEN to BLUE and then back to RED. When the LED_SEL[1:0] input signals select a specific color, the NMOSFETs are controlled based on the color selected, and a 10-bit current control DAC for this color is selected that provides a control current to the RGB LEDs' feedback control network.

BBM Timing (See Register 0Bh in Figure 27) 7.3.3 LED Current Control DLPA2000 provides time-sequential circuitry to drive three LEDs with independent current control. A system based on a common anode LED configuration is shown in Figure 10 and consists of a buck-boost converter, which provides the voltage to drive the LEDs, three switches connected to the cathodes of the LEDs, an RLIM resistor used to sense the LED current, and a current DAC to control the LED current. The voltage measured at the pin V(RLIM_K) is used by the regulator loop. The STROBE DECODER controls the switch positions as described in the previous section (RGB Strobe Decoder). With all switches in the open position, the buck-boost output assumes an output voltage of 3.5 V. 18 Submit Documentation Feedback Copyright © 2014–2018, Texas Instruments Incorporated Product Folder Links: DLPA2000 DLPA2000 www.ti.com DLPS043B – JUNE 2014 – REVISED FEBRUARY 2018 For a common-anode RGB LED configuration, the buck-boost output voltage (VLED) assumes a value such that the voltage drop across the sense resistor equals: (SW4_IDAC[9:0]Ivalue + ILED) × RLIM (1) The exact value of VLED depends on the current setting and the voltage drop across the LED but is limited to 5.4 V. When the STROBE decoder switches from SW4 to SW5, the buck-boost assumes a new output voltage such that the sense voltage equals: (SW5_IDAC[9:0]Ivalue + ILED) × RLIM (SW6_IDAC[9:0]Ivalue + ILED) × RLIM (2) (3) The relationship between VIN, VLED, and MAX ILED is shown in Figure 4. 7.3.4 Calculating Inductor Peak Current To properly configure the DLPA2000 device, a 2.2-µH inductor must be connected between pin L1 and pin L2. The peak current for the inductor in steady state operation can be calculated. Equation 4 shows how to calculate the peak current I1 in step down mode operation, and Equation 5 shows how to calculate the peak current I2 in boost mode operation. VIN1 is the maximum input voltage, VIN2 is the minimum input voltage, f is the switching frequency (2.25 MHz), and L the inductor value (2.2 µH). VOUT VIN1 VOUT I I1 OUT 0.8 2 u VIN1 u f u L (4) I2 VOUT u IOUT 0.8 u VIN2 VIN2 VOUT VIN2 2 u VOUT u f u L (5) The critical current value for selecting the right inductor is the higher value of I1 and I2. Also consider that load transients and error conditions may cause higher inductor currents. This needs to be accounted for when selecting an appropriate inductor. Internally the switching current is limited to a maximum of 4 A. 7.3.5 LED Current Accuracy The LED drive current is controlled by a current digital-to-analog converter (DAC) and can be set independently for switch SW4, SW5, and SW6. The DAC is trimmed at a current of 750 mA for the DLPA2000 at code: 0x307h. The DLPA2000 current step size is 0.95 mA. First order gain-error of the DAC can be neglected, but an offset current error must be taken into account. This offset error differs depending on the used RLIM and will be ±25 mA for the DLPA2000 for a 100-mΩ current sense resistor. The max current of the DLPA2000 (SWx_IDAC[9:0] = 0x307h) is regulated to 750 mA. At the lowest setting (SWx_IDAC[9:0] = 0x001h) the current is regulated to 14 mA for the DLPA2000. For this current setting (0x001h), the absolute current error results into a large relative error; however, this is not a typical operating point. Be aware that the LED current setting not only depends on the accuracy of the RLIM resistor, but also strongly depends on the added resistance of PCB traces and soldering quality. Due to the low value of the current sense resistor RLIM, any extra introduced resistance (for example several mΩ) will result in a noticeable different LED current.

However, the forward voltage of the red diode is significantly lower (1.8 V to 2.5 V). This can lead to a current spike in the red diode when the strobe controller switches from green or blue to red because VLED is initially at a higher voltage than required to drive the RED diode. DLPA2000 provides transient current limiting for each switch to limit the current in the LEDs during the transition. The transient current limit value is controlled through the ILIM[3:0] bits in the IREG register. The same register also contains three bits to select which switch employs the transient current limiting feature. In a typical application, the transient current limit will only apply to the RED diode, and the ILIM[3:0] value will typically be set approximately 10% higher than the DC regulation current. The effect that the transient current limit has on the LED current is shown in Figure 9. 1500 1200 Current overshoot due to initially too high buck-boost output voltage 900 600 300 RED LED CURRENT (mA) RED LED CURRENT (mA) 1500 1200 900 Transient current limit active 600 300 0 0 TIME TIME Red LED current without transient current limit.

LED Driver Block Diagram 7.3.7 1.1-V Regulator (Buck Converter) The buck converter creates a voltage of 1.1 V, and due to its switching nature, an output ripple with a frequency of approximately 2.25 MHz occurs on its output.

IN/IN mode is selected if the MODE pin is driven low or left unconnected; PHASE/ENABLE mode is selected if the MODE pin is driven to logic high. Table 2 and Table 3 show the logic for these modes. The main difference between both modes is that to change the rotation direction for IN/IN mode, both xIN1 and xIN2 signals must change polarity, while for PHASE/ENABLE mode, the PHASE signal must be held high while the PHASE signal is used to change rotation direction for a DC motor. In case a stepper motor is used, the sequence of OUT1 and OUT2 determines the rotation direction. The motor position is changed by using the internal, register-generated, control signals AIN1 and AIN2 (register 0F[123:122] in combination with BIN1 and BIN2 (register 0F[121:120]. Table 2.

If this analog current limit persists for a longer period of time than the overcurrent deglitch time, all FETs in the Hbridge will be disabled. After approximately 1 ms, the bridge will be re-enabled automatically. 7.3.9 Measurement System The measurement system is composed of a 10:1 analog multiplexer (MUX), a programmable-gain amplifier, and a comparator. It works together with the DPP processor to provide: • White-point correction (WPC) by independently adjusting the RGB LED currents after measuring the brightness of each color with an external light sensor • A measurement of the: – Battery voltage – LED forward voltage – Exact LED current – Temperature as derived by measuring the voltage across an external thermistor Figure 11 shows a block diagram of the measurement system. 22 Submit Documentation Feedback Copyright © 2014–2018, Texas Instruments Incorporated Product Folder Links: DLPA2000 DLPA2000 www.ti.com DLPS043B – JUNE 2014 – REVISED FEBRUARY 2018 AFE_GAIN [1:0] From host AFE_SEL[3:0] AFE PWM_IN VINA/3 VLED/3 SW4 SW5 CMP_OUT MUX To host From light sensor SENS1 SENS2 From temperature sensor Figure 11.

These circuits are described in the following sections. 7.3.10.1 Thermal Warning (HOT) and Thermal Shutdown (TSD) DLPA2000 continuously monitors the junction temperature and issues a HOT interrupt if temperature exceeds the HOT threshold. If the temperature continues to increase above the thermal shutdown threshold, all rails are disabled and the TSD bit in the INT register is set. After the temperature drops below its threshold, the system recovers and waits for the DPP to resend the DMD_EN bit.

Definition of the Thermal Shutdown and Hot-Die Temperature Warning 7.3.10.2 Low Battery Warning (BAT_LOW) and Undervoltage Lockout (UVLO) If the battery voltage drops below the BAT_LOW threshold (typically 3.0 V) the BAT_LOW interrupt is issued, but normal operation continues. After the battery drops below the undervoltage threshold which has a default hardcoded value of 2.3 V (this UVLO voltage can be changed through register 09h from 2.3 V to 4.5 V), the UVLO interrupt is issued, all rails are powered down in sequence, the DMD_EN bit is reset, and the part enters STANDBY mode. The power rails cannot be re-enabled before the input voltage recovers to >2.4 V. To re-enable the rails, the PROJ_ON pin must be toggled. The undervoltage threshold is programmable from 2.3 V to 4.5 V in 31 steps. The UVLO shutdown process will protect the DMD by allowing time for the mirrors to park, then doing a fast discharge of VOFS, VRST, and VBIAS. This protection occurs even in the case of sudden battery removal from the projector, as long as the bulk capacitance on the battery voltage (VINx) keeps this voltage above 2.3 V for as long as needed for VOFS, VRST, and VBIAS to discharge to the required safe levels as shown in the DMD data sheet. VOFS, VRST, and VBIAS discharge times depend on the load capacitance on each regulator. When for instance every supply is decoupled using a capacitor of 0.5 µF, VINx should stay above 2.3 V for at least 100 µs after the battery is suddenly removed. During this time, the mirrors can be placed in a safe position and VOFS, VRST, and VBIAS can be discharged. NOTE As required by the DMD data sheet, LS_OUT must stay above 1.65 V until VOFS, VRST, and VBIAS have discharged to their required safe levels. 24 Submit Documentation Feedback Copyright © 2014–2018, Texas Instruments Incorporated Product Folder Links: DLPA2000 DLPA2000 www.ti.com DLPS043B – JUNE 2014 – REVISED FEBRUARY 2018 VINA Hysteresis BAT_LOW Threshold Hysteresis UVLO Threshold ACTIVE BAT LOW (Internal Signal) UVLO (Internal Signal) INACTIVE 200-µs deglitch ACTIVE INACTIVE Programmable Deglitch Time1 A.

UVLO is Asserted When the Input Supply Drops Below the UVLO Threshold 7.3.10.3 DMD Regulator Fault (DMD_FLT) The DMD regulator is continuously monitored to check if the output rails are in regulation and if the inductor current increases as expected during a switching cycle. If either one of the output rails drops out of regulation (for example, due to a shorted output) or the inductor current does not increase as expected during a switching cycle (due to a disconnected inductor), the DMD_FLT interrupt bit is set in the INT register, the DMD_EN bit is reset, and the DMD regulator is shut down. Resetting the DMD_EN bit also causes the LED driver to power down. To restart the system, the PROJ_ON pin must be toggled. In case the interrupt is masked, it is sufficient to set the DMD_EN bit to restart the system. 7.3.10.4 V6V Power-Good (V6V_PGF) Fault The LED driver regulation loop requires the V6V rail for proper operation. The rail is continuously monitored and should the output drop below the power-good threshold, the V6V_PGF bit is set. The VLED buck-boost is then disabled and attempts to restart automatically. 7.3.10.5 VLED Overvoltage (VLED_OVP) Fault If the buck-boost output voltage rises above 5.4 V, the VLED_OVP interrupt is set but the buck-boost regulator is not turned off. A typical condition to cause this fault is an open LED. 7.3.10.6 VLED Power Save Mode In normal PWM operation, the efficiency of the VLED buck-boost converter dramatically reduces for LED currents below 100 mA. In this case, the power save mode allows high converting efficiency at low output currents by skipping pulses in the switcher’s gate driver control. 7.3.10.7 V1V8 PG Failure If for any reason the voltage on the LS_OUT drops below approximately 1.3 V, then VOFS, VBIAS, and VRST immediately go into fast shut down. Holding off power down to do mirror parking is not included since 1.3 V is too low to wait for this. Reactivating can only be done by toggling the PROJ_ON off and on again. 7.3.10.8 Interrupt Pin (INTZ) The interrupt pin is used to signal events and fault conditions to the host processor. Whenever a fault or event occurs in the IC, the corresponding interrupt bit is set in the INT register, and the open-drain output is pulled low. The INTZ pin is released (returns to HiZ state) and fault bits are cleared when the INT register is read by the host. However, if a failure persists, the corresponding INT bit remains set and the INTZ pin is pulled low again after a maximum of 32 µs. Submit Documentation Feedback Copyright © 2014–2018, Texas Instruments Incorporated Product Folder Links: DLPA2000 25 DLPA2000 DLPS043B – JUNE 2014 – REVISED FEBRUARY 2018 www.ti.com Interrupt events include fault conditions such as power-good faults, over-voltage, over-temperature shutdown, and UVLO. For all interrupt conditions see the interrupt register on Figure 28. The MASK register is used to mask events from generating interrupts, that is, from pulling the INTZ pin low. The MASK settings affect the INTZ pin only and have no impact on protection and monitor circuits themselves. When an interrupt is masked, the event causing the interrupt still sets the corresponding bit in the INT register. However, it does not pull the INTZ pin low. 7.3.10.9 SPI DLPA2000 provides a 4-wire SPI port that supports high-speed serial data transfers up to 33.3 MHz. Support includes register and data buffer write and read operations. The SPI_CSZ input serves as the active low chip select for the SPI port. The SPI_CSZ input must be forced low in order to write or read registers and data buffers. When SPI_CSZ is forced high, the data at the SPI_DIN input is ignored, and the SPI_DOUT output is forced to a high-impedance state. The SPI_DIN input serves as the serial data input for the port; the SPI_DOUT output serves as the serial data output. The SPI_CLK input serves as the serial data clock for both the input and output data. Data is latched at the SPI_DIN input on the rising edge of SPI_CLK, while data is clocked out of the SPI_DOUT output on the falling edge of SPI_CLK. Figure 14 shows the SPI port protocol. Byte 0 is referred to as the command byte, where the most significant bit is the write/not read bit. For the W/nR bit, a 1 indicates a write operation, while a 0 indicates a read operation. The remaining seven bits of the command byte are the register address targeted by the write or read operation. The SPI port supports write and read operations for multiple sequential register addresses through the implementation of an auto-increment mode. As shown in Figure 14, the auto-increment mode is invoked by simply holding the SPI_CSZ input low for multiple data bytes. The register address is automatically incremented after each data byte transferred, starting with the address specified by the command byte. After reaching address 0x7Fh the address pointer jumps back to 0x00h.

SPI Protocol 7.3.11 Password Protected Registers Register addresses 0x11h through 0x27h can be read-accessed the same way as any other register, but are protected against accidental write operations through the PASSWORD register (address 0x10h). To write to a protected register, follow these steps: 1. Write data 0xBAh to register address 0x10h. 2. Write data 0xBEh to register address 0x10h. Both writes must be consecutive, that is, there must be no other read or write operation in between sending the two bytes. After the password has been successfully written, registers 0x11h through 0x27h are unlocked and can be write accessed using the regular SPI protocol. They remain unlocked until any byte other than 0xBAh is written to the PASSWORD register or the part is power cycled. To check if the registers are unlocked, read back the PASSWORD register. If the data returned is 0x00h, the registers are locked. If the PASSWORD register returns 0x01h, the registers are unlocked. 26 Submit Documentation Feedback Copyright © 2014–2018, Texas Instruments Incorporated Product Folder Links: DLPA2000 DLPA2000 www.ti.com DLPS043B – JUNE 2014 – REVISED FEBRUARY 2018 7.4 Device Functional Modes Table 5. Modes of Operation MODE DESCRIPTION OFF This is the lowest-power mode of operation.

The IC will enter OFF mode whenever the PROJ_ON pin is low. STANDBY The DMD regulators and LED power (VLED) are turned off, but the IC does respond to the SPI. The device enters STANDBY mode whenever PROJ_ON is set high or DMD_EN (1) bit is set to 0 using the SPI interface after PROJ_ON is already high. The device also enters STANDBY mode when a fault condition is detected (2). (See Protection Circuits). ACTIVE1 The DMD supplies are enabled but LED power (VLED) is disabled.

PROJ_ON pin must be high and DMD_EN and VLED_EN bits must both be set to 1. (1) (2) (3) Settings can be done through Reg01h [9] and Reg2E [119]. Power-good faults, over-voltage, overtemperature shutdown, and undervoltage lockout. Settings can be done through Reg47h [60], bit is named VLED_EN_SET. Table 6. Device State as a Function of Control-Pin Status PROJ_ON PIN STATE LOW OFF HIGH STANDBY ACTIVE1 ACTIVE2 (Device state depends on DMD_EN and VLED_EN bits and whether there are any fault conditions.)

B. FAULT = Undervoltage on any supply (except LS_OUT), thermal shutdown, or UVLO detection. C. UVLO detection, per the diagram, causes the DLPA2000 to go into the standby state. This is not the lowest power state. If lower power is desired, PROJ_ON should be set low. D. DMD_EN register bit can be reset or set by SPI writes. DMD_EN defaults to 0 when PROJ_ON goes from low to high and then the DPP ASIC software automatically sets it to 1. Also, FAULT = 1 causes the DMD_EN register bit to be reset. E. PWR_EN is a signal internal to the PAD200x. This signal turns on the VCORE regulator and the load switch that drives pin LS_OUT. Figure 15.

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 8.1 Application Information A DLPC343x controller can be used with a DLP2010 (0.2 WVGA) DMD or DLP3010 (0.3 720p) DMD to provide a compact, reliable, high-efficiency display solution for many different video display applications. The DMDs are spatial light modulators which reflect incoming light from an illumination source to one of two directions with the primary direction being into collection optics within a projection lens. The projection lens sends the light to the destination needed for the application. Each application is derived primarily from the optical architecture of the system and the format of the pixel data being input into the DLPC343x. In display applications using the DLP2010 DMD or DLP3010 DMD, the DLPA2000 provides all needed analog functions including the analog power supplies and the RGB LED driver to provide a robust and efficient display solution. Display applications of interest include pico-projectors embedded in display devices like smart phones, tablets, cameras, and camcorders. Other applications include wearable (near-eye) displays, battery-powered mobile accessories, interactive displays, low latency gaming displays, and digital signage. Alternately, a DLPC150 controller can be used with a DLP2010 or DLP2010NIR DMD. Applications of interest when using the DLPC150 controller include machine vision systems, spectrometers, skin analysis, medical systems, material identification, chemical sensing, infrared projection, and compressive sensing. In a spectroscopy application the DLPC150 controller and DLP2010NIR DMD are often combined with a single element detector to replace expensive InGaAs array-based detector designs. In this application the DMD acts as a wavelength selector reflecting specific wavelengths of light into the single point detector. 8.2 Typical Projector Application A common application when using DLPA2000 with DLP2010 DMD and DLPC3430 controller is for creating a pico-projector embedded in a handheld product. For example, a pico-projector may be embedded in a smart phone, a tablet, a camera, or camcorder. The DLPC3430 in the pico-projector embedded module typically receives images from a host processor within the product as shown in Figure 42. DLPA2000 provides power supply sequencing and controls the LED currents as required by the application.

The DLPC3430 or DLPC3435 does the digital image processing, the DLPA2000 provides the needed analog functions for the projector, and DMD is the display device for producing the projected image. In addition to the three DLP chips in the chipset, other chips may be needed. At a minimum, a flash part is needed to store the software and firmware to control the DLPC3430 or DLPC3435. The illumination light that is applied to the DMD is typically from red, green, and blue LEDs. These are often contained in three separate packages, but sometimes more than one color of LED die may be in the same package to reduce the overall size of the pico-projector. When connecting the DLPC3430 or DLPC3435 to the host processing to receive images, a parallel interface is used. While using the parallel interface, I2C should be connected to the host processor for sending commands to the DLPC3430 or DLPC3435. The only power supplies needed external to the projector are the battery (SYSPWR) and a regulated 1.8-V supply. The entire pico-projector can be turned on and off by using a single signal called PROJ_ON. When PROJ_ON is high, the projector turns on and begins displaying images. When PROJ_ON is set low, the projector turns off and draws just microamps of current on SYSPWR. When PROJ_ON is set low, the 1.8-V supply can continue to be left at 1.8 V and used by other non-projector sections of the product. If PROJ_ON is low, the DLPA2000 will not draw current on the 1.8-V supply. 8.2.2 Detailed Design Procedure For connecting together the DLP2010, DLPC3430 or DLPC3435, and DLPA2000, see the reference design schematic. When a circuit board layout is created from this schematic, a very small circuit board is possible. An example small board layout is included in the reference design database. Layout guidelines should be followed to achieve a reliable projector. The optical engine that has the LED packages and the DMD mounted to it is typically supplied by an optical OEM who specializes in designing optics for DLP projectors. A miniature stepper motor can optionally be added to the optical engine for creating a motorized focus. Direct control and driving of the motor can be done by the DLPA2000, and software commands sent over I2C to the DLPC3430 or DLPC3435 are available to move the motor to the desired position. 42 Submit Documentation Feedback Copyright © 2014–2018, Texas Instruments Incorporated Product Folder Links: DLPA2000 DLPA2000 www.ti.com DLPS043B – JUNE 2014 – REVISED FEBRUARY 2018 Typical Projector Application (continued) 8.2.3 Application Curve As the LED currents that are driven time-sequentially through the red, green, and blue LEDs are increased, the brightness of the projector increases. This increase is somewhat non-linear, and the curve for typical white screen lumens changes with LED currents is as shown in Figure 43. For the LED currents shown, it is assumed that the same current amplitude is applied to the red, green, and blue LEDs.

Luminance vs Current 8.3 Typical Mobile Sensing Application A typical embedded system application using the DLPC150 controller and the DLPC2010NIR is shown in Figure 44. In this configuration, the DLPC150 controller supports a 24-bit parallel RGB input, typical of LCD interfaces, from an external source or processor. The DLPC150 controller processes the digital input image and converts the data into the format needed by the DLP2010NIR. The DLP2010NIR steers light by setting specific micromirrors to the on position, directing light to the detector, while unwanted micromirrors are set to the off position, directing light away from the detector. The microprocessor sends binary images to the DLP2010NIR to steer specific wavelengths of light into the detector. The microprocessor uses an analog-to-digital converter to sample the signal received by the detector into a digital value. By sequentially selecting different wavelengths of light and capturing the values at the detector, the microprocessor can then plot a spectral response to the light.

Typical Application Diagram 8.3.1 Design Requirements All applications using the DLP 0.2-inch WVGA chipset require the: • DLPC150 controller, and • DLPA2000 PMIC, and • DLP2010 or DLP2010NIR DMD components for operation. The system also requires an external parallel flash memory device loaded with the DLPC150 configuration and support firmware. DLPC150 does the digital image processing and formats the data for the DMD. DLPA2000 PMIC provides the needed analog functions for the DLPC150 and DLP2010 or DLP2010NIR. The chipset has several system interfaces and requires some support circuitry. The following interfaces and support circuitry are required: • • • 44 DLPC150 system interfaces: – Control interface – Trigger interface – Input data interface – Illumination interface DLPC150 support circuitry and interfaces: – Reference clock – PLL – Program memory flash interface DMD interfaces: – DLPC150 to DMD digital data – DLPC150 to DMD control interface – DLPC150 to DMD micromirror reset control interface Submit Documentation Feedback Copyright © 2014–2018, Texas Instruments Incorporated Product Folder Links: DLPA2000 DLPA2000 www.ti.com DLPS043B – JUNE 2014 – REVISED FEBRUARY 2018 Typical Mobile Sensing Application (continued) 8.3.2 Detailed Design Procedure 8.3.2.1 Dlpc150 System Interfaces The 0.2-inch WVGA chipset supports a 16-bit or 24-bit parallel RGB interface for image data transfers from another device. There are two primary output interfaces: Illumination driver control interface and sync outputs. 8.3.2.1.1 Control Interface The 0.2-inch WVGA chipset supports I2C commands through the control interface. The control interface allows another master processor to send commands to the DLPC150 controller to query system status or perform realtime operations, such as LED driver current settings. 8.3.3 Application Curve In a reflective spectroscopy application, a broadband light source illuminates a sample and the reflected light spectrum is dispersed onto the DLP2010NIR. A microprocessor in conjunction with the DLPC150 controls individual DLP2010NIR micromirrors to reflect specific wavelengths of light to a single point detector. The microprocessor uses an analog-to-digital converter to sample the signal received by the detector into a digital value. By sequentially selecting different wavelengths of light and capturing the values at the detector, the microprocessor can then plot a spectral response to the light. This systems allows the measurement of the collected light and derive the wavelengths absorbed by the sample. This process leads to the absorption spectrum shown in Figure 45. Figure 45.

To avoid insufficient supply current due to line drop, ringing due to trace inductance at the VIN terminal, or supply peak current limitations, additional bulk capacitance may be required. In the case ringing that is caused by the interaction with the ceramic input capacitors, an electrolytic or tantalum type capacitor may be needed for damping. The amount of bulk capacitance required should be evaluated such that the input voltage can remain in specification long enough for a proper fast shutdown to occur for the VOFS, VRST, and VBIAS supplies. The shutdown begins when the input voltage drops below the programmable UVLO threshold such as when the external power supply or battery supply is suddenly removed from the system. 46 Submit Documentation Feedback Copyright © 2014–2018, Texas Instruments Incorporated Product Folder Links: DLPA2000 DLPA2000 www.ti.com DLPS043B – JUNE 2014 – REVISED FEBRUARY 2018 10 Layout 10.1 Layout Guidelines As for all chips with switching power supplies, the layout is an important step in the design, especially in the case of high peak currents and high switching frequencies. If the layout is not carefully done, the regulators could show stability problems as well as EMI problems. Therefore, use wide and short traces for the main current paths and for the power ground tracks. Input capacitors, output capacitors, and inductors should be placed as close as possible to the IC. Figure 46 shows an example layout that has critical parts placed as close as possible to the pins they are connected to. Here are recommendations for the following components: R1 is RLIM and is connected via a wide trace and as short as possible to the DLPA2000 and the ground. L1 is the big inductor for the VLED that is connected via two wide traces to the pins. C3/C4 are the decoupling capacitors for the VLED and they are as close as possible placed to the part and directly connected to ground. L3/C20 are components used for the VCORE BUCK. L3 is placed close to the pin and connected with a wide trace to the part. C20 is placed directly beside the inductor and connected to the PGND pin. L2 This inductor is part of the DMD reset regulators and is also placed as close as possible to the DLPA2000 using wide PCB traces.
