Texas Instruments TMDSDCDCLEDKITThe LED DC/DC Developer's Kit is a DIMM100 controlCARD based motherboard evaluation module which uses Piccolo F28035. It includes all of the hardware and software to start experimenting and developing a digitally controlled LED DC/DC system. One Piccolo MCU is able to directly control the DC/DC power stage as well as eight LED strings. The development board takes 12-48V DC of input and uses a SEPIC DC/DC topology to buck or boost the input voltage to a desired level. This voltage is then fed to four LED driving stages, each capable of driving two LED strings at up to 30 Watts each. The kit includes closed loop, open source software for both the DC/DC stage and the LED lighting stage. The hardware design is also completely open source, with the gerbers, schematics, and BOMs available for free.
Software and hardware collateral are available through controlSUITE.
