| BOOT | 1 | 3 | I | Bootstrap input | Provides the gate voltage for the high side N-FET. |
| NC | 2, 3 | 5 | — | Not Connected | Pins are not electrically connected inside the chip. Pins do function as thermal conductor. |
| FB | 4 | 6 | I | Feedback pin | Feedback input to regulator. |
| EN | 5 | 7 | I | Enable input | Used to control regulator start-up and shutdown. See Precision Enable and UVLO section of data sheet. |
| GND | 6 | 4 | — | Ground input to regulator; system common |
System ground pin. |
| VIN | 7 | 2 | I | Input Voltage | Input supply to regulator |
| SW | 8 | 1 | O | Switch pin | Switching output of regulator |
| EP | EP | EP | — | Exposed Pad | Connect to ground. Provides thermal connection to PCB. See Thermal Considerations. |
