TPS542951PWP Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS542951PWP 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 TPS542951PWP to operate is 4.5V, but it's recommended to keep it above 5V for reliable startup and operation.
  • The TPS542951PWP 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 TPS542951PWP can be calculated using the formula: VOUT = 0.8V x (1 + RFBT/RFB), where RFBT and RFB are the feedback resistors.
