XL9504 from XLSEMI, in a TO-252-5L. 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 | GND | power_in | Ground pin. |
| 2 | CS | input | Output current sense pin with a 0.23V CS reference voltage, setting IOUT = 0.23/RCS. |
| 3 | SW | output | Power switch output pin and the switching node of the output power stage. |
| 4 | VC | passive | Internal voltage regulator bypass capacitor pin, requiring a 1uF capacitor connected between VIN and VC. |
| 5 | VIN | power_in | Power supply input pin supporting a 5V to 45V DC operating range, requiring a capacitor in parallel between VIN and GND to suppress noise. |
