XL8004 LED照明恒流驱动应用电路

Introduction 

The document describes a high efficiency LED driver designed to drive an LED driver at a current of 300&600 mA 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 conditions. Design with very low parts count.
