General Description of XL8002 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.
Features of XL8002● 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.
Applications of XL8002
● LED Lighting & LED LAMP
● General purpose LED lighting
