TIDM-RGB-LED Reference Design

Texas Instruments

Multi-String RGB LED Lighting Driver based on C2000™ MCU

Description

Ideal for automotive: entertainment: retail: and decorative lighting applications: the Multi-String RGB LED Lighting design implements independent multi-string LED control with dimming and color mixing. The LED driver consists of 8 independent and digitally controlled DC/DC power converters driving 8 LED strings.

Features
  • Independently drive up to 8 LED strings: including light color mixing with RGB LED strings.Suitable design reference for color or white LED applications. DC/DC LED driver power supply consists of 6 Boost DC/DC converters for driving red: green: and blue LED strings and 2 SEPIC DC/DC converters for driving white LED strings.DC/DC LED driver power supply supports 12 – 18 VDC (nominal) input and 50 mA max driver current per stringOver-current protection to protect board components from damaging current levelsPrecise LED dimming control: and robust RGB LED color mixing made possible by the C2000™ Piccolo™ TMS320F28027 microcontroller.LED lighting reference platform is available for purchase and includes hardware platform: software examples and libraries: graphical user interface (GUI): technical application notes: and step-by-step theory-based user guides.NOTE: Software for this board is located inside the controlSUITE™ software package.
