STEVAL-ILL067V1: 6-Ch 70mA @ 36V (Max), 6 ~ 32V in, Boost


The purpose of this evaluation board is to provide 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.).
