TPS54428DRCT Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS54428DRCT is 18V, but it's recommended to keep it below 15V for optimal performance and reliability.
  • To ensure stability, make sure to follow the recommended layout and component selection guidelines in the datasheet, and add a 10nF ceramic capacitor between the VIN and GND pins to filter out noise.
  • The minimum input capacitance required is 10uF, but it's recommended to use a 22uF or larger capacitor to ensure stable operation and minimize input voltage ripple.
  • Yes, the TPS54428DRCT is rated for operation up to 125°C, but the maximum junction temperature (TJ) should not exceed 150°C. Ensure proper thermal design and heat sinking to prevent overheating.
  • The output voltage can be adjusted by changing the resistor divider ratio between the FB and VOUT pins. Use the formula in the datasheet to calculate the required resistor values for the desired output voltage.
