General Description of XL8004
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 reliability.
The document describes a high efficiency LED driver designed to drive an LED driver at a current of 300&600mA from an input voltage range of 24 VDC to80 VDC, output support 3~8 series 1/3W LED.
The XL8004 also provides a sophisticated range of protection features including auto-restart for control loop open/short faults and output short-circuit conditions. Accurate hysteretic thermal shutdown ensures safe average PCB temperatures under all cond itions. Design with very low parts count.
