General Description
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 enablefunction, an over current protection function is built inside. An internal compensation block is built in to minimize external component count.
