Pin Functions
| PIN | I/O | DESCRIPTION | |
|---|---|---|---|
| NAME | NO. | ||
| EN | 1 | I | Enable input (High=Enabled, Low=Disabled). Do not leave floating. |
| FB | 2 | I | Output voltage feedback. Connect resistive voltage divider to this pin. |
| AGND | 3 | Signal ground. Internally connected to the PGND pin. Can be left floating. | |
| NC | 4 | Internally not connected. Can be connected to VOUT, GND or left floating. | |
| PGND | 5 | Power | Power ground |
| SW | 6 | Power | Switch node, connected to the internal MOSFET switches. |
| VIN | 7 | Power | Supply voltage |
| PG | 8 | O | Power good output. If unused, leave floating or connect to GND. |
