8682l Ic Datasheet (2026 Update)

The GATE pin sends a high-frequency signal to an external N-channel MOSFET.

The 8682L usually comes in a small-outline package (SOP-8 or similar). While you should always verify with the manufacturer’s markings, the standard pin functions are as follows: Pin Number Description Main power supply input. GATE Output to the gate of the external MOSFET. GND System ground. CS Current sense input for monitoring LED current. OVP Over-voltage protection threshold input. EN/DIM Enable and PWM dimming control pin. COMP Compensation pin for stability loops. VCC Internal regulator output/bypass capacitor. Technical Specifications 8682l ic datasheet

Check the EN (Enable) pin for a high signal (usually >2V) and ensure VIN is present. The GATE pin sends a high-frequency signal to
