STEVAL-ILL067V1, Evaluation Board for Six-channel ALED7707-based LED driver with embedded boost converter for automotive interior lighting and TFT backlighting

Descripción

• STEVAL-ILL067V1, Evaluation Board is to provides an application example of a six-channel, medium-current LED driver using the ALED7707 chip. The monolithic boost converter provides the required LED supply voltage starting from a single supply rail, while the brightness of the LED strings connected to the six outputs is controlled through a PWM signal. Open LED and LED short-circuit fault conditions are detected and managed. The board has been designed to provide a compact reference solution for automotive applications involving several LEDs arranged in multiple strings (e.g. interior lighting, infotainment LCD backlighting, etc.)
