TPS65251-2RHAT Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the VIN pin is 18V, but it's recommended to keep it below 15V for optimal performance and reliability.
  • To ensure the device is in a low-power state during shutdown, make sure the EN pin is pulled low and the VIN pin is disconnected from the power source.
  • The minimum input capacitance required for stable operation is 10uF, but it's recommended to use a 22uF or larger capacitor to ensure stability across the entire operating range.
  • Yes, the TPS65251-2RHAT is rated for operation up to 125°C, but the device's performance and reliability may degrade at high temperatures. Ensure proper thermal design and heat sinking to maintain optimal performance.
  • The output voltage can be configured by connecting resistors R1 and R2 between the FB pin and the output voltage rail. Use the formula in the datasheet to calculate the resistor values for the desired output voltage.
