- 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.
