Driving a light-emitting diode (LED) or LED array is not without its challenges. The LEDs require a well-designed constant-current source for controlled brightness. More specifically, the output ...

This application note presents a closed light regulation loop using LED and MLX75305 in a minimal number of components. It provides a design example for prototype and evaluation, and describes ...

While not exact, a mathematical model gives the designer a good starting point for designing the compensation of a WLED current-regulating boost converter. In addition, the designer can measure the ...

Promoting high current accuracy and consistent brightness, the HV9963 LED driver employs a closed-loop system with PWM dimming capability to optimize performance and efficiency as well as extend LED ...
