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
