Description
The Atmel LED DriversMSL3163 and MSL3164 compact, high-power LED string drivers use internal current control MOSFETs to sink up to 100mA per string, with current accuracy and matching better than 3%.
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 through the serial interf.
