TPS54122RHLT Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS54122RHLT is 60V, but it's recommended to keep it below 50V 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 1uF ceramic capacitor between VOUT and GND.
  • The minimum input voltage required for the TPS54122RHLT to operate is 4.5V, but it's recommended to keep it above 5V for reliable operation.
  • The TPS54122RHLT is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as temperature increases to ensure reliable operation.
  • The output voltage of the TPS54122RHLT can be adjusted by changing the resistive divider ratio between the VOUT pin and the GND pin, using the formula: VOUT = 0.8V x (R1 + R2) / R2.
