TPS54972PWP Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS54972PWP is 18V, but it's recommended to keep it below 15V for optimal performance and reliability.
  • 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 ESR required for the output capacitor is 0.05 ohms, but it's recommended to use a capacitor with an ESR of 0.01 ohms or less for optimal performance.
  • The TPS54972PWP is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at high temperatures to ensure reliability.
  • The output voltage of the TPS54972PWP can be calculated using the formula: VOUT = 0.8V x (1 + R1/R2), where R1 and R2 are the resistors in the feedback network.
