| description: | |
| The RT5739 is a step-down switching buck converter that can deliver the |
| programmable output voltage from 300mV to 1300mV with wide input voltage |
| supply of 2.5V to 5.5V. It can provide up to 3.5A continuous current |
| capability at over 80% high efficiency. |

| If property is present, use the 'VSEL1' register group for buck control. |
| Else, use the 'VSEL0' register group. This depends on external hardware |
| 'VSEL' pin connection. |
