XL8004 - XLSEMI

XL8004 80V 1A Switching Current Buck PFM LED Constant Current Driver

The XL8004 is a monolithic high voltage switching regulator with PFM that is specifically designed to operate from a 24V~80V DC supply. The XL8004 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. Figure1. Package.
