Led drivers circuit electronics projects based on IC. Led drivers projects like: constant current led driver, high power led driver, white led driver, led backlight driver and more .
This 4 channel LED driver circuit is designed using CAT4106 integrated LED driver (multi-channel LED driver) and high power dc-dc converter suitable for powering backlighting applications up to a total of 6 watts.
Up to 4 matched LED strings can be accurately programmed with uniform drive current set by a single external resistor.
The CAT4106 4 channel LED driver circuit automatically adjusts the output voltage to drive the highest forward voltage string with the minimum headroom voltage maximizing the efficiency.
