XL3001A from XLSEMI, in a SOP-8-EP. 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 sampling pin; the CS reference voltage is 0.21V, and the LED current is set as IOUT = 0.21/RCS. |
| 2 | NC | unconnected | No internal connection. |
| 3 | VC | power_out | Internal voltage regulator bypass pin; a 1uF capacitor must be connected between the VIN and VC pins. |
| 4 | VIN | power_in | Power input supporting a wide DC 8V to 45V operating range (absolute maximum VIN is -0.3 to 50V); a capacitor must be connected in parallel between VIN and GND to eliminate noise. |
| 5 | SW | output | Power switch output pin and the switching node of the output power stage; pin 5 and pin 6 are both SW. |
| 6 | SW | output | Power switch output pin and the switching node of the output power stage; pin 6 is connected internally to pin 5 as SW. |
| 7 | GND | power_in | Ground pin; pins 7 and 8 are both GND. |
| 8 | GND | power_in | Ground pin; pin 8 is paired with pin 7 as GND. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
