Analog MUX PD M08888-11 High Performance RGB Driver for DLP/LCD/LCoS Projectors Rev V4 Applications Features DLP/LCD/LCoS Projector Systems Three 2A common anode LED/laser drivers Backlight illumination Integrated 12.5 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 2 High speed 4 wire interface or I C 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. 2 The part can be programmed via I C or high speed 4-wire SPI interface.
