TPS543820RPYR Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS543820RPYR 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 device.
  • The TPS543820RPYR can deliver up to 8A of output current, but it's recommended to derate the current based on the ambient temperature and the input voltage to ensure reliable operation.
  • The output voltage of the TPS543820RPYR 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, where R1 and R2 are the resistors in the divider network.
  • The enable pin on the TPS543820RPYR is used to turn the device on or off. When the enable pin is pulled high, the device is enabled, and when it's pulled low, the device is disabled. This pin can be used to implement power sequencing or to turn off the device when not in use.
