General Dcription
The XL5003 is a monolithic high voltage
switching regulator with PFM that is
specifically digned to operate from a
reified 85V~265V AC mains supply.
The XL5003 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.
