TPS54228D Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS54228D is 42V, but it's recommended to keep it below 40V for reliable operation.
  • To ensure stability, make sure to follow the recommended layout guidelines, use a sufficient output capacitor, and add a 10nF capacitor between the VIN and EN pins. Also, ensure the input voltage is within the recommended range.
  • The minimum input voltage required for the TPS54228D to operate is 4.5V, but it's recommended to keep it above 5V for reliable operation.
  • The TPS54228D is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as the temperature increases to ensure reliable operation.
  • The output voltage of the TPS54228D can be adjusted by using a resistor divider network between the VOUT and GND pins. The recommended resistor values can be found in the datasheet.
