| 12 | description: | |
| 13 | RT4803 is a boost regulator that's designed to provide the minimum output |
| 14 | voltage, even if the input voltage is lower than the required voltage. It |
| 15 | supports boost and auto bypass mode that depends on the difference between the |
| 16 | input and output voltage. If the input is lower than the output, mode will |
| 17 | transform to boost mode. Otherwise, turn on bypass switch to enter bypass mode. |
