Pinout
8| Pin | Name | Functions | Notes |
|---|---|---|---|
| BOOT | Bootstrap capacitor | GND | A 0.1-μF bootstrap capacitor is required between the BOOT and PH pins. |
| VIN | Input voltage | POWER | 3.5- to 28-V input supply voltage. |
| EN | Enable pin | GPIO | To disable, pull below 1.25 V. Float this pin to enable. |
| SS | Slow-start pin | GPIO | An external capacitor connected to this pin sets the output rise time. |
| VSENSE | Inverting node of error amplifier | ADC | |
| COMP | Error-amplifier output and input to PWM comparator | PWMI2C | Connect frequency compensation components to this pin. |
| GND | Ground | GND | |
| PH | Internal high-side power MOSFET source | POWER |
