M08888-11 High Performance RGB Driver for DLP/LCD/LCoS Projectors • Three 2A common anode LED/laser drivers • Integrated Msps 10-bit current DACs with 6-bit programmable full scale • Real-time continuous and integrating optical power control • DC-DC control circuitry • Safety circuitry • High speed 4 wire interface or I2C • DLP/LCD/LCoS Projector Systems • Backlight illumination The M08888 is a high efficiency integrated triple channel 2A LED/laser driver for LCD/LCoS/DLP projection displays. It features automatic optical power control for consistent white balance across temperature variation and light source aging. The M08888 allows for the control of an external DC-DC converter to generate optimal light sources supply and improve overall system efficiency. An internal junction temperature monitor is also available. The part can be programmed via I2C or high speed 4-wire SPI interface.
