n 0.1V current sense voltage reference.
n Directly drive 1~18 Series 1W/3W LED.
n Excellent line and load regulation.
n Internal Optimize Power HV-MOSFET.
n Built in Thermal Shutdown Function.

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
n LED Lighting & LED LAMP
n General purpose LED lighting

Note1: Stresses greater than those listed under Maximum Ratings may cause permanent damage
to the device. This is a stress rating only and functional operation of the device at these or any
other conditions above those indicated in the operation is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect reliability.
