The MSL3163/4 drive 16 parallel strings of ten white LEDs each, for a total of 160 white LEDs per device. Sixteen interconnected devices control up to 2560 white LEDs. The MSL3163/4 adaptively controls the DC-DC converters that power the LED strings, using Atmel's Adaptive SourcePower technology. These Efficiency Optimizers minimize power use while maintaining LED current accuracy. The MSL3164 features a 20 MHz SPI serial interface, and the MSL3163 offers a 1 MHz I2C serial interface. Both interfaces support video frame-by-frame LED string intensity control for up to 16 interconnected devices to allow active area dimming. The devices include an advanced PWM engine that easily synchronizes to a video signal, and per-string phase adjustment to reduce unwanted LCD artifacts such as motion blur. Additionally, an on-chip E²PROM allows the power-up defaults to be customized throu...
