The Real-time Digital LED Control reference design demonstrates the control of three boost converters to drive three LEDs (red, blue, and green) strings. This design allows development with real-time digital control of the various LEDs which makes it perfect for any industrial or automotive application where real-time LED control is needed.
8 RGB LED design with real-time LED control
3 boost converters are used to step up the 12 V input voltage to a voltage high enough to forward bias the LEDs.
Step down power supply design for 3.3V and 5V selection via jumpers
The Capacitive Touch BoosterPack can be plugged into the design and used to control the LEDs.
Both PCB footprints and schematic symbols are available for download in a vendor neutral format, which can then be exported to the leading EDA CAD/CAE design tools using the Ultra Librarian Reader. The reader is available as a (free download.).
The UL Reader is a subset of the Ultra Librarian toolset that can generate, import, and export components and their attributes in virtually any EDA CAD/CAE format.
