Real-time Digital LED Control


Design files


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.
