TPS54294RSAT Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS54294RSAT 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 (at least 10uF), and add a 1nF-10nF capacitor between the VIN and EN pins to filter noise.
  • The minimum input voltage required for the TPS54294RSAT to operate is 4.5V, but it's recommended to keep it above 5V for reliable startup and operation.
  • The TPS54294RSAT 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 TPS54294RSAT can be adjusted by changing the resistive divider ratio between the VOUT and FB pins. Use the formula in the datasheet to calculate the required resistor values.
