XL3003E1 from XLSEMI, in a TO-252-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground pin. |
| 2 | CS | input | Output current sampling pin with 0.21V reference voltage. |
| 3 | SW | output | Power switch output pin and switch node of output power; metal tab is electrically SW. |
| 4 | VC | power_out | Internal voltage regulator bypass capacitor pin; 1μF capacitor required between VIN and VC. |
| 5 | VIN | power_in | Power supply input pin for 8V to 36V DC; electrolytic capacitor required between VIN and GND for noise elimination. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
