XL3003 Description
The XL3003 is a 220 KHz fixed frequency PWM buck (step-down) LED constant current driver, capable of driving a 4A load with high efficiency, low ripple and excellent line and load regulation. Requiring a minimum number of external ponents, the regulator is simple to use and include internal frequency pensation and a fixed-frequency oscillator. The PWM control circuit is able to adjust the duty ratio linearly from 0...
