XL Semiconductor XL6006S

Description

LED DriveThe XL6006 regulator is fixed frequencyPWM Boost (step-up) LED constant currentdriver, capable of driving Series 1W/3W/5WLED units with excellent line and loadregulation. The regulator is simple to usebecause it includes internal frequencycompensation and a fixed-frequency oscillatorso that it requires a minimum number ofexternal components to work.The XL6006 could directly drive 16 Series1W/3W LED units at VIN=24V .The PWM control circuit is able to adjust theduty ratio linearly from 0 to 90%. An enablefunction, an over current protection functionis built inside. An internal compensationblock is built in to minimize externalcomponent count.
