XL6005 180KHz 60V 4A Switching Current Boost LED Constant Current Driver
(DATASHEET)![](http://www.techcodesemi.com/taide/UploadFiles/20111001014503577.gif)
The 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 . The PWM control circuit is able to adjust the duty ratio linearly from 0 to 95%. An enable function, an over current protection function is built inside. An internal compensation block is built in to minimize external component count.
