| NAME | NO. | DESCRIPTION |
| BOOT | 1 | A 0.1 µF bootstrap capacitor is required between BOOT and PH. If the voltage on this capacitor falls below the minimum requirement, the high-side MOSFET is forced to switch off until the capacitor is refreshed. |
| VIN |
2 |
Input supply voltage, 3.5 V to 28 V. |
| EN | 3 | Enable pin. Pull below 1.25V to disable. Float to enable. Programming the input undervoltage lockout with two resistors is recommended. |
| SS | 4 | Slow start pin. An external capacitor connected to this pin sets the output rise time |
| VSENSE | 5 | Inverting node of the gm error amplifier |
| COMP | 6 | Error amplifier output, and input to the PWM comparator. Connect frequency compensation components to this pin |
| GND | 7 | Ground. |
| PH | 8 | The source of the internal high-side power MOSFET. |
