Methods of controlling multiple LED strings with C2000 microcontrollers

January 18, 2012 // By Texas Instruments

As more applications continue to integrate LED technology, developers find themselves facing the challenge of driving greater numbers of LEDs while lowering system cost and increasing power efficiency. For systems requiring multiple strings of LEDs, TI provides two example solutions illustrating differing power stage topology designs and digital control methods. This whitepaper explores the different LED driver topologies and digital control methods available for driving multiple LED strings efficiently to reduce system cost, lower operating expenses, increase color accuracy, and improve overall reliability.
