Led drivers circuit electronics projects

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 .

32 Channel LED Driver circuit using LT3746

This 32 Channel LED driver circuit project is designed using the LT3746 IC manufactured by Linear Technology, which integrates a 32 channel LED driver with a 55V buck controller. The LED driver lights up to 30mA/13V of LEDs in series per channel, and the buck controller generates an adaptive bus voltage supplying the parallel LED strings. Each channel has individual 6-bit dot correction current adjustment and 12-bit grayscale PWM dimming.

LED driver electronic project using transistors

A very simple electronic project LED driver circuit can be designed using common electronic parts like in this circuit . This electronic project LED driver circuit will drive up to 3 high-bright white LEDs from a 3v supply.

CAT3661 led driver circuit

This Led driver circuit is designed using the CAT3661 high efficiency low power LED driver, that can be used for low power LCD display backlight, or low power hand-held device backlight. CAT2261 circuit use a charge pump that drives one LED with up to 5 mA of current.
The quad-mode charge pump supports a wide range of input voltages from 2.0 V to 5.5 V.
