TPS54521RHLT Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS54521RHLT is 42V, but it's recommended to keep it below 40V for reliable operation.
  • To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, keep the input and output capacitors close to the device and use a low-ESR capacitor for the output.
  • The minimum input voltage required for the TPS54521RHLT to operate is 4.5V, but it's recommended to keep it above 5V for reliable operation.
  • The TPS54521RHLT is rated for operation up to 125°C, but the maximum junction temperature should not exceed 150°C. Make sure to follow the thermal design guidelines in the datasheet to ensure reliable operation.
  • The output voltage of the TPS54521RHLT can be calculated using the formula: Vout = 0.8V x (1 + R2/R1), where R1 and R2 are the feedback resistors.
