General Description
The XL6003 regulator is fixed frequency PWM Boost (step-up) LED constant current driver, capable of driving Series 1W LED units with excellent line and load regulation. The regulator is simple to use because it includes internal frequency pensation and a fixed-frequency oscillator so that it requires a minimum number of external ponents to work. The XL6003 could directly drive 6 Series 1W LED units at VIN>=12V .
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 pensation block is built in to minimize external ponent count.
