TPS544B20RVFR Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS544B20RVFR is 20V, but it's recommended to keep it below 18V 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 TPS544B20RVFR can deliver is 2A, but it's recommended to keep it below 1.5A for reliable operation.
  • The output voltage of the TPS544B20RVFR can be adjusted by using a resistor divider network between the output and the ADJ pin. The output voltage can be calculated using the formula: Vout = 0.8V x (R1 + R2) / R2.
  • The EN (enable) pin is used to turn the regulator on or off. When the EN pin is high, the regulator is enabled, and when it's low, the regulator is disabled.
