Methods of controlling multiple LED strings with C2000 microcontrollers
January 18, 2012 // Texas Instruments // 0 commentsDownload White Paper 532Ko
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.

This month, Trinamic Motion Control is offering you to win one of four TMCM-1043 development kits for its highly integrated, NEMA 17-compatible TMCM-1043 stepDancer stepper motor module.
Offering designers an easy-to-use PC-based GUI that allows one-click modification of motor drive current, micro-stepping and other key parameters, the intuitive kits are custom designed and developed for direct mounting on a NEMA 17 motor. Pre-programmed and pre-configured with all operating parameters to support standard 1.5A (peak) motors, the TMCM-1043 board uses Trinamic´s single-axis TMC2660 stepper motor driver IC, which integrates a motor pre-driver and power MOSFETs.
