TPS25944ARVCT Frequently Asked Questions (FAQs)

  • A good PCB layout for the TPS25944ARVCT 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 10uF, and an ESR that meets the datasheet specifications. X5R or X7R ceramic capacitors are good options.
  • The maximum output current of the TPS25944ARVCT is 4A, but it's recommended to derate the output current based on the ambient temperature and the input voltage to ensure reliable operation.
  • The output voltage of the TPS25944ARVCT can be adjusted by connecting a resistor divider network between the VOUT pin and the GND pin, and then connecting the center tap of the divider to the FB pin.
  • The EN (enable) pin is used to turn the regulator on or off. When the EN pin is high, the regulator is enabled, and when it's low, the regulator is disabled and the output voltage is disconnected from the input voltage.
