Description
The Atmel® LED DriversMSL2160 and MSL2161 compact, high-power LED string drivers use external current control MOSFETs to sink up to 350mA per string, with current accuracy and matching better than 1.5%.
Features
- a 20MHz SPI bus, and the MSL2161 offers a 1MHz I2C serial interface. Both interfaces support video frame-by-frame LED string intensity control for up to eight interconnected devices, allowing active area dimming and phase shifted PWM dimming for improved performance. Both devices include an advanced PWM engine that synchronizes PWM dimming to the video signal for reduced motion blur and waterfall noise. The MSL2160/1 adaptively controls the DC-DC converters that power the LED strings using Atmel.
