The XL8002 is a high efficiency LED driverswitching regulator. The LED string is drivenat DC constant current rather than constantvoltage, thus providing constant light outputand enhanced reliability. Features Operation Voltage DC 12V~80V. 0.1V current sense voltage reference. Directly drive 1~18 Series 1W/3W LED. Excellent line and load regulation. Internal Optimize Power HV-MOSFET. Built in Thermal Shutdown Function. Built in Current Limiting Function. Built in Soft-Start Circuit. Available in TO263-5L package. Up to 98% efficiency. 0
