Figure 1-3. DLP LightCrafter Driver Board Block Diagram
The major components of the DLP LightCrafter’s driver board are:
• DLP3000: 0.3-inch WVGA chipset DMD
• DLPC300: 0.3-inch WVGA chipset controller for DLP3000 with:
– 2MB SPI FLASH that contains DLPC300 firmware
– 32MB mDDR that buffers images for the DLP3000
• MSP430:
– Controls power supply sequencing and system initialization
– Shuts down system upon detection of low or high input voltage
– Shuts down system if LED anode voltages exceed maximum limit
– Measures thermistor and shuts down system when maximum temperature ratings are exceeded
• LED driver circuitry
• Power management:
– TPS63020: Buck-Boost Regulator for LED supplies
– TPS63020: Buck-Boost Regulator for 3.3 V supply
– TPS62260: Step Down Converter for DLPC300 2.5 V supply
– TPS62400: Step Down Converter for DLPC300 1.0 V and 1.8 V supply
– TPS65120: 4-CH Bias for DMD VRST and VBIAS supplies
– TPS71501: LDO for DMD VOFS supply
