The Atmel mSilica MSL2100 compact, high-power LED string driver uses external MOSFETs to provide up to 1A per string, with current accuracy and matching better than ±1%. The MSL2100 drives eight parallel strings of LEDs, and offers fault detection and management of open and short circuit LEDs. The MSL2100 features a 1MHz I2C serial interface. The interface supports video frame-by-frame LED string intensity control for up to 16 interconnected devices, allowing active area dimming when used for video displays. The advanced PWM engine synchronizes with the video signal, and offers phase shifted string drive, virtually eliminating waterfall noise and motion blur. The MSL2100 adaptively controls up to three DC-DC converters, which power the LED strings, using patented mSilica Adaptive SourcePower™ technology. These Efficiency Optimizers minimize power use while maintaining LED current accuracy, and allow up to 16 interconnected devices to automatically negotiate the optimum power supply voltages.
