TPS543C20RVFR Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS543C20RVFR is 42V, but it's recommended to keep it below 40V for reliable operation.
  • To ensure the stability of the output voltage, make sure to use a suitable output capacitor with a low ESR (Equivalent Series Resistance) and a minimum capacitance of 10uF. Also, ensure that the input capacitor is properly sized and placed close to the VIN pin.
  • The minimum input voltage required for the TPS543C20RVFR to operate is 6.5V, but it's recommended to keep it above 7V for reliable startup.
  • The TPS543C20RVFR is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at higher temperatures to ensure reliable operation.
  • The output voltage of the TPS543C20RVFR can be calculated using the formula: VOUT = 0.8V x (1 + R1/R2), where R1 and R2 are the resistors connected to the FB pin.
