XL6003 datasheet


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 compensation and a fixed-frequency oscillator so that it requires a minimum number of external components to work.

The driver could directly drive 6 Series 1W LED units at VIN>12V .
