Pin Functions
| PIN | I/O | DESCRIPTION | |
|---|---|---|---|
| NAME | NO. | ||
| BOOT | 7 | I/O | Supply input for high-side NFET gate drive circuit. Connect 0.1-µF ceramic capacitor between VBST and SW pins. |
| EN | 1 | I | Enable input control. Pull High to enable converter. |
| FB | 2 | I | Converter feedback input. Connect to output voltage with resistor divider. |
| GND | 5 | – | Power ground |
| SCL | 4 | I/O | Clock I/O terminal. |
| SDA | 3 | I/O | Data I/O terminal. |
| SW | 6 | I/O | Switch node connections for both the high-side NFET and low–side NFET. |
| VIN | 8 | I | Input voltage supply pin. |
| PowerPAD™ | – | – | Thermal pad of the package. Must be soldered down to operate normally and achieve appropriate power dissipation. Connect sensitive FB returns to GND at a single point. |
