This application report presents a solution to control an LED lighting system using TMS320F2802x microcontrollers. The Piccolo™ TMS320F2802x series of devices are part of the family of C2000 microcontrollers, which enables cost-effective designs of LED lighting systems. With these devices, it is possible to control multiple strings of LEDs in an efficient and very accurate way. In addition to this, the speed of the C2000 microcontroller allows it to integrate many supplemental tasks that would, in a normal system, increase chip count and complexity. These tasks could include DC/DC conversion stages, AC/DC conversion stages with PFC, system management, and various communication protocols such as DALI, DMX512, KNX or even power line communication (PLC). On the board described in this document, eight independent DC/DC stages (6x Boost, 2x Sepic) are use to drive eight individual LED strings.

This application report covers the following:

  • A brief overview of LED Lighting technology
  • The advantages C2000 can bring to a lighting system
  • How to run and get familiar with the Multi-DC/DC Color LED Kit's LED-ColorMix project
