8682l Ic Datasheet ❲2025❳

To ensure the 8682L operates safely within a circuit, adhere to these typical electrical limits: 10V to 30V (varies by sub-model).

Generally fixed or set via external resistor. Dimming Range: 0% to 100% via PWM signal. Operating Temperature: -40°C to +85°C. Typical Application Circuit 8682l ic datasheet

Prevents damage during surges. Short-Circuit Protection: Safeguards the IC and LEDs. High Efficiency: Low power dissipation during operation. Pin Configuration and Descriptions To ensure the 8682L operates safely within a

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 Operating Temperature: -40°C to +85°C

The CS (Current Sense) pin monitors the voltage across a resistor in series with the LEDs to maintain constant brightness.

💡 If you cannot find the 8682L specifically, look for "OB8682" or similar prefixes, as different manufacturers use slightly different naming conventions for this specific controller architecture.
