General Description
The XL6002 is a 150KHz fixed frequency PWM buck / buck_boost LED driver, capable
of driving a 2A load with high efficiency, low ripple and excellent line and load regulation. Requiring a minimum number of external components, the regulator is simple to use and include internal frequency compensation and a fixed-frequency oscillator.
The PWM control circuit is able to adjust the duty ratio linearly from 0 to 100%. An PWM
dimming function, an over current protection function is built inside. An internal
compensation block is built in to minimize external component count.
