XL5004 Overview
The XL5004 is a monolithic high voltage switching controller with PFM that is specifically designed to operate from a rectified 85V~265V AC mains supply. The XL5004 is a high efficiency LED driver switching controller. The LED string is driven at DC constant current rather than constant voltage, thus providing constant current output and enhanced reliability.
