XL5003 Datasheet (XLSEMI) - 600V 0.5A Switching Current Buck PFM LED Constant Current Driver

XL5003, 600V 0.5A Switching Current Buck PFM LED Constant Current Driver

The XL5003 is a monolithic high voltage switching regulator with PFM that is specifically designed to operate from a rectified 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
