This is an advanced regulation topology that combines the advantages of hysteretic and voltage mode control. The DCS-Control™ topology operates in PWM (Pulse Width Modulation) mode for medium to heavy load conditions and in PSM (Power Save Mode) at light load currents. In PWM mode, the converter operates with its nominal switching frequency of 2.0 MHz having a controlled frequency variation over the input voltage range. As the load current decreases, the converter enters Power Save Mode, reducing the switching frequency and minimizing the IC's quiescent current to achieve high efficiency over the entire load current range. DCS-Control™ supports both operation modes using a single building block and therefore has a seamless transition from PWM to PSM without effects on the output voltage. The TPS82150 offers excellent DC voltage regulation and load transient regulation, combined with low output voltage ripple, minimizing interference with RF circuits. 7.2 Functional Block Diagram space space PG VIN VFB High Side Current Sense VREF EN (1) 400kΩ Bandgap Undervoltage Lockout Thermal Shutdown L (2) MOSFET Driver Control Logic VIN Ramp SS/TR Voltage Clamp VREF Timer ton Direct Control and Compensation FB Comparator Error Amplifier DCS - Control VOUT 22pF TM VREF GND Note: (1) When the device is enabled, the 400 kΩ resistor is disconnected.

This tON, in steady-state operation in PWM and PSM modes, is estimated as: space t ON = 500ns ´ VOUT VIN (1) space In PWM mode, the TPS82150 operates with pulse width modulation in continuous conduction mode (CCM) with a tON shown in Equation 1 at medium and heavy load currents. A PWM switching frequency of typically 2.0MHz is achieved by this tON circuitry. The device operates in PWM mode as long as the output current is higher than half the inductor's ripple current estimated by Equation 2. space DIL = t ON ´ VIN - VOUT L (2) space To maintain high efficiency at light loads, the device enters Power Save Mode seamlessly when the load current decreases. This happens when the load current becomes smaller than half the inductor's ripple current. In PSM, the converter operates with reduced switching frequency and with a minimum quiescent current to maintain high efficiency. PSM is also based on the tON circuitry. The switching frequency in PSM is estimated as: space fPSM = 2 ´ IOUT V - VOUT V t ON2 ´ IN ´ IN VOUT L (3) space In PSM, the output voltage rises slightly above the nominal output voltage in PWM mode. This effect is reduced by increasing the output capacitance. The output voltage accuracy in PSM operation is reflected in the electrical specification table and given for a 22-µF output capacitor. For very small output voltages, an absolute minimum on-time of about 80ns is kept to limit switching losses. The operating frequency is thereby reduced from its nominal value, which keeps efficiency high. Also the off-time can reach its minimum value at high duty cycles. The output voltage remains regulated in such cases. When VIN decreases to typically 15% above VOUT, the TPS82150 can't enter Power Save Mode, regardless of the load current. The device maintains output regulation in PWM mode. 7.3.2 Low Dropout Operation (100% Duty Cycle) The TPS82150 offers a low input to output voltage differential by entering 100% duty cycle mode. In this mode, the high-side MOSFET switch is constantly turned on. This is particularly useful in battery powered applications to achieve longest operation time by taking full advantage of the whole battery voltage range. The minimum input voltage to maintain a minimum output voltage is given by: space VIN(min) = VOUT(min) + IOUT ´ RDP (4) space Where RDP = Resistance from VIN to VOUT, including high-side FET on-resistance and DC resistance of the inductor VOUT(min) = Minimum output voltage the load can accept. 8 Submit Documentation Feedback Copyright © 2017, Texas Instruments Incorporated Product Folder Links: TPS82150 TPS82150 www.ti.com SLVSDN4 – JUNE 2017 Feature Description (continued) 7.3.3 Switch Current Limit The switch current limit prevents the device from high inductor current and from drawing excessive current from the battery or input voltage rail. Excessive current might occur with a heavy load/shorted output circuit condition. If the inductor peak current reaches the switch current limit after a propagation delay of typically 30ns, the highside FET is turned off and the low-side FET is turned on to ramp down the inductor current. 7.3.4 Undervoltage Lockout To avoid mis-operation of the device at low input voltages, an under voltage lockout is implemented, which shuts down the devices at voltages lower than VUVLO with a hysteresis of 200mV. 7.3.5 Thermal Shutdown The device goes into thermal shutdown and stops switching once the junction temperature exceeds TJSD. Once the device temperature falls below the threshold by 20°C, the device returns to normal operation automatically. 7.4 Device Functional Modes 7.4.1 Enable and Disable (EN) The device is enabled by setting the EN pin to a logic High. Accordingly, the shutdown mode is forced if the EN pin is pulled Low with a shutdown current of typically 1.5 μA. An internal pull-down resistor of 400kΩ is connected to the EN pin when the EN pin is Low. The pull-down resistor is disconnected when the EN pin is High. 7.4.2 Soft Startup (SS/TR) The internal voltage clamp controls the output voltage slope during startup. This avoids excessive inrush current and ensures a controlled output voltage rise time. When the EN pin is pulled high, the device starts switching after a delay of typically 55μs and the output voltage rises with a slope controlled by an external capacitor connected to the SS/TR pin. Using a very small capacitor or leaving the SS/TR pin floating provides fastest startup time. The TPS82150 is able to start into a pre-biased output capacitor. During the pre-biased startup, both the power MOSFETs are not allowed to turn on until the internal voltage clamp sets an output voltage above the pre-bias voltage. When the device is in shutdown, undervoltage lockout or thermal shutdown, the capacitor connected to SS/TR pin is discharged by an internal resistor. Returning from those states causes a new startup sequence. 7.4.3 Voltage Tracking (SS/TR) The SS/TR pin is externally driven by another voltage source to achieve output voltage tracking. The application circuit is shown in Figure 4. VOUT1 VOUT2 TPS82150 R3 R1 SS/TR FB R2 R4 Figure 4. Output Voltage Tracking Submit Documentation Feedback Copyright © 2017, Texas Instruments Incorporated Product Folder Links: TPS82150 9 TPS82150 SLVSDN4 – JUNE 2017 www.ti.com Device Functional Modes (continued) When the SS/TR pin voltage is between 50 mV and 1.2 V, the VOUT2 tracks the VOUT1 as described in Equation 5. space VOUT 2 R2 R3 + R4 » 0.64 ´ ´ R1 + R2 R4 VOUT1 (5) space When the SS/TR pin voltage is above 1.2 V, the voltage tracking is disabled and the FB pin voltage is regulated at 0.8 V. For decreasing SS/TR pin voltage, the device doesn't sink current from the output. So the resulting decreases of the output voltage may be slower than the SS/TR pin voltage if the load is light. When driving the SS/TR pin with an external voltage, do not exceed the voltage rating of the SS/TR pin which is VIN+0.3V. Details about tracking and sequencing circuits are found in SLVA470. 7.4.4 Power Good Output (PG) The device has a power good (PG) output. The PG pin goes high impedance once the output is above 95% of the nominal voltage, and is driven low once the output voltage falls below typically 90% of the nominal voltage. The PG pin is an open drain output and is specified to sink up to 2mA. The power good output requires a pull-up resistor connecting to any voltage rail less than 6V. The PG pin goes low when the device is in shutdown or thermal shutdown. When the device is in UVLO, the PG pin is high impedance. The PG signal can be used for sequencing of multiple rails by connecting it to the EN pin of other converters. Leave the PG pin floating when it is not used. Table 1 shows the PG pin logic. Table 1.

Start by entering your VIN, VOUT, and IOUT requirements. 2. Optimize your design for key parameters like efficiency, footprint and cost using the optimizer dial and compare this design with other possible solutions from Texas Instruments. 3. The WEBENCH Power Designer provides you with a customized schematic along with a list of materials with real time pricing and component availability. 4. In most cases, you will also be able to: – Run electrical simulations to see important waveforms and circuit performance – Run thermal simulations to understand the thermal performance of your board – Export your customized schematic and layout into popular CAD formats – Print PDF reports for the design, and share your design with colleagues 5. Get more information about WEBENCH tools at www.ti.com/WEBENCH. 8.2.1.2.2 Setting the Output Voltage The output voltage is set by an external resistor divider according to the following equations: space R1 ö R1 ö æ æ VOUT = VFB ´ ç 1 + = 0.8 V ´ ç 1 + ÷ R2 ø R2 ÷ø è è (6) space R2 should not be higher than 100kΩ to achieve high efficiency at light load while providing acceptable noise sensitivity. Larger currents through R2 improve noise sensitivity and output voltage accuracy. Figure 5 shows the external resistor divider value for a 1.8-V output. Choose appropriate resistor values for other outputs. In case the FB pin gets opened, the device clamps the output voltage at the VOUT pin internally to about 7V. 8.2.1.2.3 Input and Output Capacitor Selection For best output and input voltage filtering, low ESR ceramic capacitors are required. The input capacitor minimizes input voltage ripple, suppresses input voltage spikes and provides a stable system rail for the device. A 10-µF or larger input capacitor is required. The output capacitor value can range from 22μF up to more than 400μF. Higher values are possible as well and can be evaluated through the transient response. Larger soft start times are recommended for higher output capacitances. High capacitance ceramic capacitors have a DC Bias effect, which will have a strong influence on the final effective capacitance. Therefore the right capacitor value has to be chosen carefully. Package size and voltage rating in combination with dielectric material are responsible for differences between the rated capacitor value and the effective capacitance. 8.2.1.2.4 Soft Startup Capacitor Selection A capacitance connected between the SS/TR pin and the GND allows programming the startup slope of the output voltage. A constant current of 2.5 μA charges the external capacitor. The capacitance required for a given soft startup time for the output voltage is given by: space CSS / TR = t SS / TR ´ 12 ISS / TR 1.25 V (7) Submit Documentation Feedback Copyright © 2017, Texas Instruments Incorporated Product Folder Links: TPS82150 TPS82150 www.ti.com SLVSDN4 – JUNE 2017 8.2.1.3 Application Performance Curves 100 100 90 90 Efficiency (%) Efficiency (%) TA = 25°C, VIN = 12 V, VOUT = 1.8 V, unless otherwise noted. 80 70 60 50 1m 80 70 60 VIN = 3.3 V VIN = 5.0 V VIN = 12 V IOUT = 0.1 A IOUT = 1.0 A 50 10m 100m 3 1 Load (A) 5 100 100 90 90 80 70 60 15 17 D019 80 70 IOUT = 0.1 A IOUT = 1.0 A 50 10m 100m 3 1 5 7 D002 Figure 8.

As the former GND node now represents a voltage level below system ground, the voltage difference between VIN and VOUT has to be limited for operation to the maximum supply voltage of 17V (see Equation 8). space VIN + VOUT £ VIN max (8) space space VIN VIN VOUT R3 TPS82150 PG R1 CIN EN COUT FB R2 SS/TR GND CSS - VOUT Copyright © 2017, Texas Instruments Incorporated Figure 30. Inverting Power Supply Schematic space The transfer function of the inverting power supply configuration differs from the buck mode transfer function, incorporating a Right Half Plane Zero additionally. Therefore the loop stability has to be adapted. More detailed information is given in TIDUCV2. Submit Documentation Feedback Copyright © 2017, Texas Instruments Incorporated Product Folder Links: TPS82150 17 TPS82150 SLVSDN4 – JUNE 2017 www.ti.com 9 Power Supply Recommendations The devices are designed to operate from an input voltage supply range between 3V and 17V. The average input current of the TPS82150 is calculated as: space IIN = 1 VOUT ´ IOUT ´ h VIN (9) space Ensure that the power supply has a sufficient current rating for the applications. 10 Layout 10.1 Layout Guidelines • • • • TI recommends placing all components as close as possible to the IC. The input capacitor placement specifically, must be closest to the VIN and GND pins of the device. Use wide and short traces for the main current paths to reduce the parasitic inductance and resistance. To enhance heat dissipation of the device, the exposed thermal pad should be connected to bottom or internal layer ground planes using vias. Refer to Figure 31 for an example of component placement, routing and thermal design. 10.2 Layout Example space space C3 VIN C1 R2 EN SS/TR VIN PG GND FB VOUT VOUT R1 VOUT GND C2 Figure 31.

The amount of current derating is dependent upon the input voltage, output power, PCB layout design and environmental thermal condition. Care should especially be taken in applications where the localized PCB temperature exceeds 65°C. The TPS82150 module temperature must be kept less than the maximum rating of 125°C. Three basic approaches for enhancing thermal performance are below: • Improve the power dissipation capability of the PCB design. • Improve the thermal coupling of the TPS82150 to the PCB. • Introduce airflow into the system. To estimate approximate module temperature of TPS82150, apply the typical efficiency stated in this datasheet to the desired application condition to find the module's power dissipation. Then calculate the module temperature rise by multiplying the power dissipation by its thermal resistance. For more details on how to use the thermal parameters in real applications, see the application notes: SZZA017 and SPRA953.
