The Multi-DC/DC Color LED Kit is a DIMM100 controlCARD based motherboard evaluation module which uses Piccolo F28027. It includes all of the hardware and software to start experimenting and developing a digitally controlled multi-DC/DC LED lighting system. One Piccolo MCU is able to directly control eight separate DC/DC power stages as well as up to eight LED strings of various LED types and string lengths. The development board takes 12-24V DC input and employs six Boost and two SEPIC DC/DC power stage topologies to drive LED strings. An included graphical user interface allows users to quickly begin the evaluation process by providing simplified control to adjust power stage current levels for experimentation with brightness and color mixing. The kit includes open source, closed loop software examples for the control of the DC/DC power stages and LED lighting stages. The hardware design is also open source, with the gerbers, schematics, and BOMs available for free.
Software and hardware collateral are available through controlSUITE.
