Real-time Digital LED Control

TIDM-LPBP-LEDDRIVER

Design files

Overview

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.

Features

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.
