TPS54872PWP Frequently Asked Questions (FAQs)

  • TI provides a recommended PCB layout in the datasheet (Figure 23) and in the TPS54872PWP Evaluation Module User's Guide (SLUU444). Follow these guidelines to minimize noise, ensure proper thermal management, and optimize performance.
  • Choose input capacitors with low ESR (Equivalent Series Resistance) and high ripple current rating. For output capacitors, select ones with low ESR, high capacitance, and a voltage rating above the output voltage. Refer to the datasheet (Section 7.2) for more information and capacitor selection guidelines.
  • The TPS54872PWP is rated for operation up to 85°C ambient temperature. However, it's essential to consider the device's thermal management and ensure proper heat dissipation to maintain reliable operation.
  • The soft-start feature is enabled by connecting the SS pin to a capacitor to GND. The soft-start time is determined by the capacitor value and the internal resistor (R_SS). Refer to the datasheet (Section 7.3.5) for more information and calculation guidelines.
  • The EN (Enable) pin is used to turn the device on or off. Connect EN to a logic high (VIN or a voltage above 1.2 V) to enable the device, and connect it to a logic low (GND) to disable it. Use a pull-down resistor to ensure the device is disabled during power-up.
