MSL3085
Description
The Atmel LED Driver MSL3085 pact, highpower 8 LED strings controller uses external MOSFETs to sink up to 350m A per string, with current accuracy and matching better than ±1.5%. The MSL3085 drives eight parallel strings of LEDs, and offers fault detection and management of open and short circuit LEDs.
The MSL3085 features a 1MHz I2C serial interface. The interface supports video frame-by-frame LED string intensity control for up to eight interconnected devices, allowing active area dimming and phase shifted PWM timing for video displays. It includes an advanced PWM engine that synchronizes LED timing with the video signal for reduced motion blur and waterfall noise. The MSL3085 adaptively controls the DC-DC converters that power the LED strings using patented Atmel Adaptive Source Power™ technology. These fault monitored efficiency optimizers minimize power use while maintaining LED current accuracy, and allow up to eight interconnected devices to automatically negotiate...
