Preliminary Datasheet
80V 1A High Efficiency Buck PFM LED Constant Current Driver
XL8002
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.

General Description
The XL8002 is a monolithic high voltage
switching regulator with PFM that is
specifically designed to operate from a
12V~80V DC power supply.
The XL8002 is a high efficiency LED driver
switching regulator. The LED string is driven
at DC constant current rather than constant
voltage, thus providing constant light output
and enhanced reliability.
Applications
„ LED Lighting & LED LAMP
„ General purpose LED lighting
