Texas InstrumentsTMDSDCDCLEDKITEingebettete Systementwicklungsboards und -kits

The LED DC/DC Developer's Kit includes all of the hardware and software to start experimenting and developing a digitally controlled LED DC/DC system. The kit is based on the Piccolo microcontroller and the controlCARD development platform. 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 kit hardware is also completely open source, with the gerbers, schematics, and BOMs all available for free
