Pin Configuration
| Pin Name |
Pin Number |
Description |
| SW |
1 |
Power Switch Output. SW is the drain of the internal MOSFET switch. Connect the power inductor and output rectifier to SW. SW can swing between GND and 22V. |
| GND |
2 |
Ground Pin |
| FB |
3 |
Feedback Input. The FB voltage is 0.6V. Connect a resistor divider to FB. |
| EN |
4 |
Regulator On/Off Control Input. A high input at EN turns on the converter, and a low input turns it off. When not used, connect EN to the input supply for automatic startup. |
| VIN |
5 |
Input Supply Pin. Must be locally bypassed. |
| OC |
6 |
Adjustable Current Limit (Floating Available). |
