TPS54231DRG4 Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS54231DRG4 is 42V, but it's recommended to keep it below 40V for reliable operation.
  • To ensure the stability of the output voltage, make sure to use a suitable output capacitor with a low ESR (Equivalent Series Resistance) and a sufficient capacitance value, as recommended in the datasheet.
  • The EN (Enable) pin is used to enable or disable the regulator. Connect it to a logic high (VIN or higher) to enable the regulator, and connect it to a logic low (GND) to disable it.
  • The output voltage of the TPS54231DRG4 can be calculated using the formula: VOUT = 0.8V x (1 + R1/R2), where R1 and R2 are the resistors connected to the FB (Feedback) pin.
  • The maximum output current that the TPS54231DRG4 can deliver is 3A, but it's recommended to keep it below 2.5A for reliable operation.
