| 13 | The AW2013 is a 3-channel LED driver with I2C interface. It can control |
| 14 | LED brightness with PWM output. |

| 33 | "VIO1" in the typical application circuit example of the datasheet. |
| 34 | Note that this regulator does not directly connect to AW2013, but is |
| 35 | needed for the correct operation of the interrupt and I2C lines. |
