General Description

The XL8004 is a monolithic high voltage

switching regulator with PFM that is

specifically designed to operate from a

24V~80V DC supply.

The XL8004 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 reliabil
