XL9522 from XLSEMI, in a SOP-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 | CS | input | Output current sense pin with a CS reference voltage of 0.23V (IOUT = 0.23/RCS). |
| 2 | EN | input | Enable pin, active low: low level operates, high level shuts down, and it is treated as low when floating (VEN_H 1.4V shutdown, VEN_L 0.8V on). |
| 3 | VC | passive | Internal voltage regulator bypass capacitor pin, requiring a 1uF capacitor connected between VIN and VC. |
| 4 | VIN | power_in | Power supply input pin supporting a 5V to 45V DC operating range, requiring an electrolytic capacitor between VIN and GND to suppress noise. |
| 5 | SW | power_out | Power switch output pin, the switching node of the output power stage. |
| 6 | SW | power_out | Power switch output pin, the switching node of the output power stage. |
| 7 | GND | power_in | Ground pin. |
| 8 | GND | power_in | Ground pin. |
