TPS25944LRVCR Frequently Asked Questions (FAQs)

  • A good PCB layout for the TPS25944LRVCR involves placing the input capacitors close to the VIN pin, using a solid ground plane, and keeping the high-current paths short and wide. TI provides a recommended layout in the datasheet and application notes.
  • Choose an input capacitor with a voltage rating that exceeds the maximum input voltage, a capacitance value between 4.7uF to 22uF, and an ESR that meets the datasheet specifications. X5R or X7R ceramic capacitors are good options.
  • The maximum output current of the TPS25944LRVCR is 4A, but it's recommended to derate the output current based on the ambient temperature and the PCB's thermal design. Refer to the datasheet for thermal derating curves.
  • The output voltage of the TPS25944LRVCR can be adjusted by connecting a resistor divider network between the VOUT pin and the GND pin. The datasheet provides a formula to calculate the required resistor values for a specific output voltage.
  • The EN (enable) pin is used to turn the regulator on or off. Connect the EN pin to a logic high (VIN or a voltage above 1.4V) to enable the regulator, or connect it to a logic low (GND) to disable it.
