General Description
The XL8003 is a monolithic high voltage switching regulator with PFM that is specifically designed to operate from a 24V~80V DC supply. The XL8003 is a high efficiency LED driver switching regulator. The LED string is driven at DC constant current rather than constant voltage, thus providing constant current output and enhanced reliability.
Wide 24V to 80V Input Voltage Range 0.2V current sense voltage reference. Directly drive 3~8 series 1W LED. Excellent line and load regulation. High efficiency up to 96%. Internal optimize power HV-MOSFET....
