TPS543B20RVFT Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS543B20RVFT 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 minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, use a low-ESR capacitor for the input capacitor.
  • The maximum output current that the TPS543B20RVFT can deliver is 2A, but it's recommended to keep it below 1.5A for reliable operation.
  • The output voltage of the TPS543B20RVFT can be adjusted by using a resistor divider network between the output and the feedback pin. The output voltage can be calculated using the formula: Vout = 0.8V x (R1 + R2) / R2.
  • The enable pin (EN) on the TPS543B20RVFT is used to turn the device on or off. When the EN pin is high, the device is enabled, and when it's low, the device is disabled.
