title: Richtek RT4803 Boost Regulator

maintainers:

description: |
  RT4803 is a boost regulator that's designed to provide the minimum output
  voltage, even if the input voltage is lower than the required voltage. It
  supports boost and auto bypass mode that depends on the difference between the
  input and output voltage. If the input is lower than the output, mode will
  transform to boost mode. Otherwise, turn on bypass switch to enter bypass mode.
