TPS54231DR Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the TPS54231DR 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 the VIN and GND pins.

  • The minimum input capacitance required is 10uF, but it's recommended to use a 22uF or larger capacitor to ensure stable operation.

  • Yes, the TPS54231DR is rated for operation up to 125°C, but the maximum junction temperature (TJ) should not exceed 150°C. Ensure proper thermal design and heat sinking to prevent overheating.

  • The output voltage can be adjusted by changing the resistor divider ratio between the FB and VOUT pins. Use the formula in the datasheet to calculate the required resistor values.
