PRODUCTION DATA.
| PIN | TYPE | DESCRIPTION | |
|---|---|---|---|
| NAME | NO. | ||
| INBK1 | 1, 2 | — | Buck 1 converter (V(IO)) supply pin. This pin is internally connected to INBK3. Place a buffer capacitor close to this pin. |
| NC | 3 | — | Not connected. |
| SDA | 4 | I / O | I2C data pin. |
| SCL | 5 | I | I2C clock pin. |
| A0 | 6 | I | I2C address select pin. |
| HVS | 7 | I | Boost and Buck 3 converter High Voltage Stress Mode enable pin. |
| INVL | 8 | — | Internal logic supply pin. Place a buffer capacitor close to this pin. |
| AGND | 9 | — | Analog Ground pin. Internal circuitry uses this ground. |
| COMP | 10 | I / O | Boost converter (V(AVDD)) compensation pin. |
| VL | 11 | I / O | Internal 5 V regulator output pin. Connect a buffer capacitor to this pin. |
