| PIN | NAME | FUNCTION |
| 1 | LX | Power Switch Output. LX is the drain of the internal MOSFET switch. Connect the power inductor and output rectifier to LX. LX can swing between GND and 28V. |
| 2 | GND | Ground Pin |
| 3 | FB | Feedback Input. The FB voltage is 0.6V. Connect a resistor divider to FB. |
| 4 | EN | 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. |
| 5 | IN | Input Supply Pin. Must be locally bypassed. |
| 6 | NC | Not Connection |
