XL6006S

Datasheet 180KHz 60V 5A Switching Current Boost LED Constant Current Driver XL6006 Features 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 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 XL6006 could directly drive 16 Series 1W/3W LED units at VIN=24V . „ „ „ „ „ „ „ „ „ „ „ Wide 5V to 32V Input Voltage Range Maximum Boost Output Up to 60V 0.22V FB adjustable LED drive current Directly drive 16 Series 1W/3W LED at VIN=24V Fixed 180KHz Switching Frequency Max. 5A Switching Current Capability Up to 94% efficiency Excellent line and load regulation EN PIN TTL shutdown capability Internal Optimize Power MOSFET Built in Soft-Start Function Built in Frequency Compensation Built in Thermal Shutdown Function Built in Current Limit Function Available in TO263-5L package 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.
