8682l Ic Datasheet ((new)) -

In a standard LED driver circuit, the 8682L acts as the "brain." The IC receives voltage at the VIN pin.

The 8682L is a high-performance, programmable constant current LED driver controller typically found in modern lighting systems and backlight units. Because it is a specialized component, understanding its pinout and electrical characteristics is vital for repair or circuit design. 8682L IC Overview 8682l ic datasheet

The OVP pin monitors the output rail; if the LED string breaks, the IC shuts down to prevent a voltage spike. Troubleshooting Tips In a standard LED driver circuit, the 8682L

Check the EN (Enable) pin for a high signal (usually >2V) and ensure VIN is present. 8682L IC Overview The OVP pin monitors the

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

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
