TPS54228DDA Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS54228DDA 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-22nF capacitor between the VIN and EN pins to filter out noise.
  • The minimum input voltage required for the TPS54228DDA to operate is 4.5V, but it's recommended to keep it above 5V for reliable startup and operation.
  • Yes, the TPS54228DDA can operate in high-temperature environments up to 125°C, but the output current may need to be derated to prevent overheating.
  • The output voltage of the TPS54228DDA can be adjusted by using a resistive divider network between the VOUT and GND pins, and the FB pin. The recommended resistors are 1% tolerance or better.
