The Multi-DC/DC Color LED Kit includes all of the hardware and software to start experimenting and developing a digitally controlled multi-DC/DC LED lighting system. This kit is based on the Piccolo microcontroller and the controlCARD development platform. 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. The six separate Boost stages drive two RGB LED strings, controlling the red, green, and blue color components of each RGB LED string. The two SEPIC stages drive two white LED strings. Alternatively, up to eight separate white LED strings could be driven via the eight separate power stages. 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. Furthermore, through controlSUITETM
, the kit includes closed loop, open source software examples for the control of the DC/DC power stages and LED lighting stages. The kit hardware is also completely open source, with the gerbers, schematics, and BOMs all available for free. For more information, please see the quick start guide for the kit.
