| 12 | description: | |
| 13 | The RT5120 provides four high-efficiency buck converters and one LDO voltage |
| 14 | regulator. The device is targeted at providingthe processor voltage, memory, |
| 15 | I/O, and peripheral rails in home entertainment devices. The I2C interface is |
| 16 | used for dynamic voltage scaling of the processor voltage, power rails on/off |
| 17 | sequence control, operation mode selection. |
