        180KHz 60V 4A Switching Current Boost LED Constant

Current Driver XL6005E1

        The XL6005E1 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.

        Features
   1） Wide 3.6V to 32V Input Voltage Range
   2） 0.22V FB adjustable LED drive current
   3） Directly drive 11 Series 1W LED at VIN>=12V
   4） Fixed 180KHz Switching Frequency
   5） Max. 4A Switching Current Capability
   6） Up to 94% efficiency
   7） Excellent line and load regulation
   8） EN PIN TTL shutdown capability & With PWM Dimming Function
   9） Internal Optimize Power MOSFET
 10） Built in Soft-Start Function
 11） Built in Frequency Compensation
 12） Built in Thermal Shutdown Function
 13） Built in Current Limit Function
14） Available in TO252-5L package

       Applications
