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 high voltage white LED driver circuit is based on the NCP5021 IC manufactured by On Semiconductor. This NCP5021 high voltage white LED driver circuit is designed with ambient light sensing feature.
The NCP5021 is capable of driving up to 8 LEDs in series for portable backlight applications.
The built−in DC DC converter is based on a high efficient PWM boost structure with 32 V output voltage span.
