TPS54331DDAR Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the TPS54331DDAR is 42V, but it's recommended to keep it below 40V for reliable operation.

  • To ensure stability, make sure to follow the recommended layout and component selection guidelines in the datasheet, and add a 10uF ceramic capacitor between VIN and GND, and a 22uF ceramic capacitor between VOUT and GND.

  • The minimum input voltage required for the TPS54331DDAR to operate is 6.5V, but it's recommended to keep it above 7V for reliable operation.

  • Yes, the TPS54331DDAR can operate in high-temperature environments up to 125°C, but the output current may need to be derated to prevent overheating.

  • The output voltage of the TPS54331DDAR can be adjusted by using a resistor divider network between the VOUT and GND pins, and the FB pin. The datasheet provides a formula to calculate the required resistor values.
