PRODUCTION DATA.
| PIN | DESCRIPTION | |
|---|---|---|
| NAME | NO. | |
| GND | 1 | Ground pin Source terminal of low-side power NFET as well as the ground terminal for controller circuit. Connect sensitive VFB to this GND at a single point. |
| SW | 2 | Switch node connection between high-side NFET and low-side NFET. |
| VIN | 3 | Input voltage supply pin. The drain terminal of high-side power NFET. |
| VFB | 4 | Converter feedback input. Connect to output voltage with feedback resistor divider. |
| EN | 5 | Enable input control. Active high and must be pulled up to enable the device. |
| VBST | 6 | Supply input for the high-side NFET gate drive circuit. Connect 0.1 µF capacitor between VBST and SW pins. |
