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 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.
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.
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.
