XL9612

XLSEMI · LED Drivers · TO-252-5L

XL9612 from XLSEMI, in a TO-252-5L. 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 power stage and control circuitry; tie to the system ground plane.
2 CS input Output current sense pin. The internal loop regulates the voltage across RCS to a 0.22V reference (±3%), setting IOUT = 0.22V / RCS. Absolute max VCS is -0.3V to 7V.
3 SW output Power switch output pin. Switching node of the synchronous buck power stage; connects to the external inductor. Also internally tied to the TO252 metal tab.
4 VC passive Internal voltage regulator bypass capacitor pin. A 1uF ceramic capacitor is required between VIN and VC to bypass the internal LDO/regulator that supplies gate drive and control circuitry.
5 VIN power_in Power supply input pin. Supports a wide DC input range of 5V to 72V (absolute max 90V). Requires an electrolytic bypass capacitor between VIN and GND for noise suppression.
