# LP6230BMSF

**LOWPOWER** · DC-DC Converters · MSOP-8

LP6230BMSF from LOWPOWER, in a MSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No connection. |
| 2 | FB | input | Regulation feedback input; connect to an external resistive divider from the output to FB to set the output voltage (0.6V feedback reference). |
| 3 | EN | input | Regulator on/off control input; logic high (VEN>1.4V) turns on the regulator, logic low (VEN<0.4V) puts it into low current shutdown mode. |
| 4 | GND | power_in | Ground. |
| 5 | SW | passive | Switching pin connected to the internal power MOSFET (rated 22V to GND). |
| 6 | VIN | power_in | Power supply pin; supply input voltage range 2.2V to 6V. |
| 7 | NC | unconnected | No connection. |
| 8 | NC | unconnected | No connection. |
