General Description
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.
