Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground pin; source terminal of low-side power NFET and ground reference for controller circuit; connect VFB feedback at single point to this GND. |
| 2 | SW | output | Switch node connection between high-side NFET and low-side NFET. |
| 3 | VIN | power_in | Input voltage supply pin with range 4.5V to 17V; drain terminal of high-side power NFET. |
| 4 | VFB | input | Converter feedback input connected to output voltage through feedback resistor divider; VFB threshold voltage 753 to 767 mV. |
| 5 | EN | input | Enable input control, active high and must be pulled up to enable device; high-level input voltage 1.6V, low-level input voltage 0.8V. |
| 6 | VBST | output | Supply input for high-side NFET gate drive circuit; connect 0.1µF capacitor between VBST and SW pins. |
