联系人：曹中立 电话：１３４２８７０６２２３ ＱＱ：１１５７００８１１５ 180KHz 60V 4A Switching Current Boost LED Constant Current Driver Datasheet XL6005 Features General Description n n n 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 . n n n n n n n n n n n Wide 3.6V to 32V Input Voltage Range 0.22V FB adjustable LED drive current Directly drive 11 Series 1W LED at VIN>=12V Fixed 180KHz Switching Frequency Max. 4A Switching Current Capability Up to 94% efficiency Excellent line and load regulation EN PIN TTL shutdown capability & With PWM Dimming Function 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 TO252-5L package 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.
