XL6006 60V 5A Switching Current Boost LED Constant Current Driver

General Description
     The XL6006 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 usebecause it includes internal frequency compensation and a fixed-frequency oscillator so that it requires a minimum number of external components to work.

     The XL6006 could directly drive 16 Series 1W/3W LED units at VIN=24V .

     The PWM control circuit is able to adjust the duty ratio linearly from 0 to 90%. An enable function, an over current protection function is built inside. An internal compensation block is built in to minimize external component count.
