General Description
The XL8003 is a monolithic high voltage
switching regulator with PFM that is
specifically designed to operate from a
24V~80V DC supply.
The XL8003 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.
