General Description
The XL5002 is a monolithic high voltage
switching regulator with PFM that is
specifically designed to operate from a
rectified 85V~265V AC mains supply.
The XL5002 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.
Applications
n E27, GU10, GU5.3, B22 lamp device
n LED Lighting & LED LAMP
n General purpose lighting
