Applications:  LED Lighting, Boost constant current driver, Monitor LED Backlighting 7 to 15 LCD Panels

Switching LED Constant Current Driver circuit diagram XL6005 regulator is fixed frequency PWM Boost (step-up) LED constant current driver, capable of driving Series 1W/3W/5W LED units with excellent line and load regulation. The regulator is simple to use because it includes internal frequency compensation and a fixed-frequency oscillator so that it requires a minimum number of external components to work. The XL6005 could directly drive 11 Series 1W LED units at VIN>12V .

Wide 3.6V to 32V Input Voltage Range, 0.22V FB adjustable LED drive current, Directly drive 11 Series 1W LED at VIN>=12V, Fixed 180KHz Switching Frequency  Max. 4A Switching Current Capability, Up to 94% efficiency, Excellent line and load regulation, EN PIN TTL shutdown capability & With PWM Dimming Function.
