| 12 | description: |
| 13 | RT5033 is a multifunction device which includes battery charger, fuel gauge, |
| 14 | flash LED current source, LDO and synchronous Buck converter for portable |
| 15 | applications. It is interfaced to host controller using I2C interface. The |
| 16 | battery fuel gauge uses a separate I2C bus. |

| 30 | The regulators of RT5033 have to be instantiated under a sub-node named |
| 31 | "regulators". For SAFE_LDO voltage there is only one value of 4.9 V. LDO |
| 32 | voltage ranges from 1.2 V to 3.0 V in 0.1 V steps. BUCK voltage ranges |
| 33 | from 1.0 V to 3.0 V in 0.1 V steps. |
