XLSEMI · LED Drivers · TO-263-5L

XL9613 from XLSEMI, in a TO-263-5L. 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. Common return for the internal control circuitry and low-side power MOSFET.
2 CS input Output current sense input. The chip regulates the voltage on this pin to a 0.22 V reference (±3%), setting LED current as IOUT = 0.22 V / RCS. Absolute maximum voltage on this pin is 7 V.
3 SW output Power switch output - switching node of the internal synchronous buck converter. Connects to the external inductor. High-side RDS(ON) ≈ 270 mΩ, low-side RDS(ON) ≈ 255 mΩ, current limit ≈ 2.2 A. Also electrically connected to the TO263-5L metal tab.
4 VC passive Internal voltage regulator bypass capacitor pin. A 1 µF ceramic capacitor must be connected between VIN and VC to decouple the internal LDO/bias supply.
5 VIN power_in Power supply input, DC 5 V to 72 V (absolute max 90 V). An electrolytic bulk capacitor must be placed between VIN and GND to filter input noise; a typical 47 µF/100 V is used in the reference design.
