Datasheet 180KHz 60V 4A Switching Current Boost LED Constant Current Driver XL6005 Features General Description n Wide 3.6V to 32V Input Voltage Range The XL6005 regulator is fixed frequency PWM n 0.22V FB adjustable LED drive current Boost (step-up) LED constant current driver, n Directly drive 11 Series 1W LED at capable of driving Series 1W/3W/5W LED units with excellent line and load regulation. The VIN= 12V regulator is simple to use because it includes internal n Fixed 180KHz Switching Frequency frequency compensation and a fixed-frequency n Max. 5A Switching Current Capability oscillator so that it requires a minimum number of n Up to 94% efficiency external components to work. n Excellent line and load regulation The XL6005 could directly drive 11 Series 1W LED n EN PIN TTL shutdown capability units at VIN 12V . With PWM Dimming Function n Internal Optimize Power MOSFET The PWM control circuit is able to adjust the n Built in Soft-Start Function duty ratio linearly from 0 to 95%. An enable n Built in Frequency Compensation function, an over current protection function n Built in Thermal Shutdown Function is built inside. An internal compensation n Built in Current Limit Function block is built in to minimize external n Available in TO252-5L package component count. Applications n LED Lighting n Boost constant
