The STEVAL-ILL035V2 product evaluation board is an extension (daughterboard) of the STEVAL-ILL035V1 (motherboard) based on the LED7708 LED driver. It allows implementation of a daisy-chained configuration for applications requiring more than 16 channels.


The LED7708 is configured as slave on the STEVAL-ILL035V2, and as master on the STEVAL-ILL035V1.


The boost controller section is not used and the supply voltage for the LED strings is derived from the motherboard (STEVAL-ILL035V1, master) by extending the output voltage optimization through dedicated hand-shake signals. Additional daughterboards can be connected to a single motherboard to increase the number of channels. The brightness control of the LED strings and the fault management options are identical to the ones available for the STEVAL-ILL035V1 evaluation board. The evaluation board is intended as a solution for medium/large LCD panel backlight drivers, but is suitable for any application involving several LEDs arranged is strings (e.g. advertisement panels, signs, gaming, etc.).
