LM3554TMEEV

User's Guide SNVA646B – January 2009 – Revised July 2013 AN-1742 LM3554 Evaluation Board 1 Introduction The Texas Instruments LM3554 Evaluation Board is designed to fully evaluate the LM3554 Synchronous Boost Converter with Dual 600 mA High Side Flash LED Drivers and I2C-Compatible Interface. For a detailed description of the LM3554, see LM3554 Synchronous Boost Converter with 1.2A Dual High Side LED Drivers and I2C-Compatible Interface (SNVS549). The board comes equipped with two LXCL-PWF4 Flash LEDs from Lumiled and an additional LED (LEDI) is an Indicator LED. The Flash Button demonstrates the Hardware Flash feature of the LM3554 and when pushed, turns on both Flash LEDs at the programmed Flash current. There are two 10-kΩ pull-up resistors on the board for the I2C clock and data lines (SDA and SCL). Additionally, there is a 10-kΩ pull-up (R_RESET) that pulls the HWEN/GPIO1 pin high during startup. Each input and/or output from the LM3554 has its own separate header to serve as a test-point. Figure 2 shows the Evaluation Board schematic. 2 Operation To operate the evaluation board, connect a 2.5V to 5.5V supply between the VL banana jack and the GND banana jack. Make sure that a jumper is installed from the VI/O pin to the IN pin (3-pin header at bottom left of board). This connects the logic level pull-ups to the VIN supply. Next, connect a jumper from the IN header and VL. This will short the IN pin and the power supply connected to the VL banana jack. This jumper is designed to remove the input bypass capacitor from the input of the inductor in order to measure the inductor current. If a supply is connected at VL, make sure that the VIN/VUSB jumper (upper right of board) is removed. This jumper takes the power from the Texas Instruments USB Interface Board and connects it to VL. With this jumper in place and a supply connected to VL, the power source from the USB Interface Board will conflict with the supply connected to VL. Control of the LM3554 can be done via two ways. At the top left corner of the board are two 2-pin headers. Each header has its left most pin connected to either the SCL or the SDA pin of the LM3554 and to the on-board pull-up resistor. The right-most pin connects to GND. To control the LM3554 using a data generator or an external I2C device, connect the I2C lines directly to the left pins of these headers (SCL and SDA). Alternatively, you can use Texas Instruments USB board. 2.1 Jumper/Header Descriptions SCL, GND Header:— SCL pin connects to SCL of the LM3554 and to the SCL line coming from the USBL connector. The on-board pull-up for SCL is 10 kΩ. The right side of this header connects to GND. SDA, GND Header:— SDA pin connects to SDA of the LM3554 and to the SDA line coming from the USBL connector. The on-board pull-up for SDA is 10 kΩ. The right side of this header connects to GND. VI/O, ENVM/TX2 Jumper:— The VI/O pin connects to the middle pin of the bottom left jumper on the board (VUSB, VI/O, IN). The right pin of this jumper connects to ENVM/TX2/GPIO2 of the LM3554. ENVM/TX2/GPIO2 has an internal 300-kΩ pull-down. All trademarks are the property of their respective owners.

If a thermistor is installed at RTH, connect the bias supply for the thermistor resistive divider at VBIAS. The right side of this pin connects to GND. VI/O, TX Jumper:— The left pin of this jumper (VI/O) connects to the middle pin of the bottom left jumper on the board (VUSB, VI/O, IN). The right pin (TX) connects directly to the TX1/TORCH input of the LM3554. There is an internal 300-kΩ pull-down resistor on TX1/TORCH. VIN/VUSB Jumper:— Left pin of this jumper connects to VL (input side of the inductor). The right pin of this jumper connects to the USB interface board's power supply. A2 Header:— The A2 header connects across a 0.1Ω current sense resistor (R2) in series with LED2. A1 Header:— The A1 header connects across a 0.1Ω current sense resistor (R1) in series with LED1. SW, GND Header:— The top pin of this header (SW) connects to the SW pin of the LM3554. The bottom pin connects to GND. IN, VL Jumper:— The left pin of this jumper connects to IN . The right pin connets to VL (input side of the inductor). This jumper connects the VL supply to CIN. VUSB, VI/O, IN Jumper:— Three-pin jumper. The left pin connects to the 3.3V supplied from the USB Interface Board. The middle pin connects to the LM3554 Evaluation Boards pull-ups. The right pin connects to IN of the LM3554. RESET, GND Jumper:— The left pin (RESET) connects to HWEN/GPIO1 of the LM3554 and to the R_RESET pull-up resistor (10 kΩ). The right pin connects to GND. Connecting a jumper here will force the LM3554 into shutdown. VI/O, STROBE Jumper:— Left pin of this jumper connects to the middle pin of the bottom left jumper on the board (VUSB, VI/O, IN). The right pin connects to the STROBE input on the LM3554. Connecting a jumper here will force the LM3554 into hardware flash mode. OUT Header:— This header connects to the OUT pin of the LM3554. 2.2 Operation with the Texas Instruments USB Interface Board The USBL and USBR connectors (16-pin bottom mounted connectors on each side of the board) plug directly into the Texas Instruments USB Interface Board. The connectors are keyed so the boards will fit together only one way. The 3-position header at the bottom left of the board (VUSB, VI/O, IN) connects the logic voltages to IN or to the 3.3V regulator (VUSB) coming from the USB board. Connecting a jumper across VIN/VUSB at the top right of the board allows for power (at the VL pin) to come from the Texas Instruments USB Interface Board. This is useful for demonstrating the device without an external power supply. This can only be used for low-current Torch and Flash currents which keep the input current below 500 mA. This is due to the 500-mA current limit available from the USB port. This input voltage from the USB Board can be 3.3V or 5V, depending on the (J1) jumper setting on Texas Instruments USB Interface Board (See USB Interface Module for Applications (SNOU007) for details). High current requirements such as the higher Flash and Torch currents require an external supply at VL. Also, ensure the VIN/VUSB jumper is left open when connecting an external supply to the VL pin when operating with Texas Instruments USB Interface Board as this will cause a conflict with the power supply from the Interface Board and the external supply connected to VL. 2 AN-1742 LM3554 Evaluation Board SNVA646B – January 2009 – Revised July 2013 Submit Documentation Feedback Copyright © 2009–2013, Texas Instruments Incorporated LM3554 Graphical User Interface www.ti.com 3 LM3554 Graphical User Interface The LM3554.exe graphical user interface program works together with the Texas Instruments USB Interface Board to provide control of the LM3554 Evaluation Board via the PC.

When this button is pushed, bit 0 in the VIN Monitor Register is set to ‘1’, and the VIN Monitor feature in the LM3554 is enabled. When the button is not pushed, bit 0 in the VIN Monitor Register is programmed with a ‘0’, and the VIN Monitor feature is disabled. The VIN Monitor Slider selects the 4 different VIN Monitor Thresholds shown in Table 6 and programs the VIN Threshold Bits (bits [2:1] of VIN Monitor Register). The box to the right of the slider shows the Hexadecimal equivalent of the VIN Threshold bits. Table 6. VIN Monitor Thresholds 4.7 UVLO Slider Setting Under Voltage Lockout Threshold 0 3.1V (Default) 1 3.2V 2 3.3V 3 3.4V Configuration Buttons The following buttons correspond to bits in the Configuration Register 1 (0xD0): 4.7.1 EXT TORCH When pushed, the EXT TORCH Button writes a ‘1’ to bit 7 (Hardware Torch Mode Enable) of Configuration Register 1. This makes the TX1/TORCH input a hardware Torch enable. When not pushed, the bit is written with a ‘1’, and the TX1/TORCH input is a transmit interrupt flash inhibit. 4.7.2 TX2 POL When pushed, the TX2 POL button writes a ‘1’ to bit 6 (TX2 Polarity bit) of Configuration Register 1. This makes the ENVM/TX2 input (when in TX2 mode) an active high flash inhibit. When not pushed, the bit is written with a ‘0’, and the ENVM/TX2 (when in TX2 mode) an active low flash inhibit. 4.7.3 TX2 When pushed, the TX2 button writes a ‘1’ to bit 5 (ENVM/TX2 bit) of Configuration Register 1. This makes the ENVM/TX2 input a transmit interrupt flash inhibit with adjustable polarity. When not pushed, the bit is written with a ‘0’, and the ENVM/TX2 input is a hardware Voltage mode enable. 4.7.4 HYST When pushed the HYST button writes a ‘1’ to bit 4 (HYST bit) of Configuration Register 1 and selects 100 mV hysteresis for the thermistor comparator. When not pushed, the bit is written with a ‘0’, and 200 mV of hysteresis is selected. 4.7.5 NTC When pushed, the NTC button writes a ‘1’ to bit 3 (LEDI/NTC bit) of Configuration Register 1 and makes the LEDI/NTC pin an input to the thermistor comparator. In this mode, when the voltage at LEDI/NTC falls below 1.05V (typical), the flash event is terminated. When not pushed, the bit is written with a zero, and the LEDI/NTC pin is an indicator current source output. 4.7.6 Dis STR When the Dis STR button is pushed, a ‘1’ is written to Bit 2 of Configuration Register 1. This disables the STROBE input. When not pushed, the STROBE input is an active high Flash mode enable.

This changes the output voltage in Voltage Output Mode to 5V when pushed or 4.5V when not pushed. 4.7.8 DisLL The DisLL button gives the option of disabling the light load comparator of the LM3554 when pushed or enabling the light load comparator when not pushed. When the light load comparator is disabled, the LM3554 will not switch over to pulse skip mode at light load currents (typically IOUT = 100 mA with VIN = 3.6V). The light load comparator only applies when the LM3554 is operating in Voltage Out mode. In LED mode the light load comparator is always disabled. 4.8 Shutdown Configuration Buttons The following buttons correspond to Configuration Register 2, address (0xF0): 4.8.1 VIN Monitor SD The VIN MONITOR SD button programs bit 3 of Configuration Register 2 with a ‘1’ when pushed, or a ‘0’ when not pushed. When this bit is a ‘1’, the LM3554 will be forced into shutdown when the VIN Monitor feature is enabled (VIN Monitor Register bit [0] = 1), and the input voltage falls below the programmed VIN Threshold. When this bit is a ‘0’, and the VIN Monitor feature is enabled, the LEDs are forced into Torch mode when the input voltage falls below the programmed VIN Threshold. 4.8.2 Alt Ext Torch When the Alt Ext Torch (Alternative External Torch) button is pushed, Configuration Register 2 bit 2 is programmed with ‘1’. This sets the LM3554 up for Alternative External Torch mode (AET mode). In AET mode the timeout counter is disabled when TX1 goes high before STROBE goes high. For example, in AET mode a high on TX1, followed by a high on STROBE, forces the LEDs into Torch mode without a timeout. If TX1 is then brought low with STROBE still high, the LEDs are forced into Flash mode, and the timeout counter is re-enabled. When STROBE is brought low, or when the timeout counter expires, the LEDs are turned off. When the Alt Ext Torch button is left un-pushed, this bit is programmed with a ‘0’, and the LM3554’s timeout function operates normally. 4.8.3 NTC SD When the NTC SD button is pushed, bit 1 of Configuration Register 2 is programmed with a ‘1’, and the LM3554 is placed in NTC Shutdown mode. When the button is not pushed, bit 1 of Configuration Register 1 is programmed with ‘0’, and the LM3554 is placed into NTC force Torch mode. When the LM3554 is placed in NTC mode (Configuration Register 1 bit 3 = 1), and NTC force shutdown mode, the LM3554 will go into shutdown when the NTC voltage falls below 1.05V. When the LM3554 is placed in NTC mode (Configuration Register 1 bit 3 = 1) and NTC force Torch mode, the LM3554 will reduce the active Flash current to the programmed Torch level if the NTC voltage falls below 1.05V. 4.8.4 TX2 SD When the TX2 SD button is pushed, Configuration Register 2 bit 0 is programmed with a ‘1’, and the LM3554 is placed in TX2 Force Shutdown mode. If the LM3554 is placed into TX2 Force Shutdown mode, and the ENVM/TX2 pin is configured as a TX2 input (Configuration Register 1, bit 5 = 1), a TX2 event causes the LM3554’s LED current to turn off. If the LM3554 is placed into TX2 force Torch mode, and the ENVM/TX2 pin is configured as a TX2 input (Configuration Register 1, bit 5 = 1), a TX2 event causes the LM3554’s LED current to go from Flash mode to Torch mode. A TX2 event is considered as a low-to-high transition at TX2 when the TX2 polarity bit is set for active high (Configuration Register 1 bit 5 = 1) or a high-to-low transition on TX2 when the TX2 polarity bit is set for active low (Configuration Register 1 bit 5 = 0). 8 AN-1742 LM3554 Evaluation Board SNVA646B – January 2009 – Revised July 2013 Submit Documentation Feedback Copyright © 2009–2013, Texas Instruments Incorporated Evaluation Board Schematic and Bill of Materials www.ti.com LED2 (PWF4) VB USBL VIN/VUSB LED1 (PWF4) RTH A2 TX1/TORCH VI/O VBIAS GND ENVM/TX2 VI/O SDA GND SCL Evaluation Board Schematic and Bill of Materials GND 5 R3 C4 LEDI USBR R_SDA (10 k:) TX1/ TORCH R_RESET (10 k:) 15 16 LED1 ENVM/ TX2 R_SCL (10 k:) COUT (10PF) OUT LM3554 STROBE 2 OUT SDA FLASH (Button) 1 A1 R1 (0.1:) R2 (0.1:) LED2 2 LEDI/ NTC 1 15 16 SW SW GND SCL SW GND IN GND /RESET L (2.2 PH) STROBE IN VL GND /RESET IN VI/O VUSB VI/O CIN (10 PF) OUT GND GND VL Figure 2.

Unless otherwise indicated, this EVM is not a finished electrical equipment and not intended for consumer use. It is intended solely for use for preliminary feasibility evaluation in laboratory/development environments by technically qualified electronics experts who are familiar with the dangers and application risks associated with handling electrical mechanical components, systems and subsystems. It should not be used as all or part of a finished end product. Your Sole Responsibility and Risk. You acknowledge, represent and agree that: 1. 2. 3. 4. You have unique knowledge concerning Federal, State and local regulatory requirements (including but not limited to Food and Drug Administration regulations, if applicable) which relate to your products and which relate to your use (and/or that of your employees, affiliates, contractors or designees) of the EVM for evaluation, testing and other purposes. You have full and exclusive responsibility to assure the safety and compliance of your products with all such laws and other applicable regulatory requirements, and also to assure the safety of any activities to be conducted by you and/or your employees, affiliates, contractors or designees, using the EVM. Further, you are responsible to assure that any interfaces (electronic and/or mechanical) between the EVM and any human body are designed with suitable isolation and means to safely limit accessible leakage currents to minimize the risk of electrical shock hazard. Since the EVM is not a completed product, it may not meet all applicable regulatory and safety compliance standards (such as UL, CSA, VDE, CE, RoHS and WEEE) which may normally be associated with similar items. You assume full responsibility to determine and/or assure compliance with any such standards and related certifications as may be applicable. You will employ reasonable safeguards to ensure that your use of the EVM will not result in any property damage, injury or death, even if the EVM should fail to perform as described or expected. You will take care of proper disposal and recycling of the EVM’s electronic components and packing materials. Certain Instructions. It is important to operate this EVM within TI’s recommended specifications and environmental considerations per the user guidelines. Exceeding the specified EVM ratings (including but not limited to input and output voltage, current, power, and environmental ranges) may cause property damage, personal injury or death. If there are questions concerning these ratings please contact a TI field representative prior to connecting interface electronics including input power and intended loads. Any loads applied outside of the specified output range may result in unintended and/or inaccurate operation and/or possible permanent damage to the EVM and/or interface electronics. Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the load specification, please contact a TI field representative. During normal operation, some circuit components may have case temperatures greater than 60°C as long as the input and output are maintained at a normal ambient operating temperature. These components include but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors which can be identified using the EVM schematic located in the EVM User's Guide. When placing measurement probes near these devices during normal operation, please be aware that these devices may be very warm to the touch.
