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.
