1.1.2 Illumination Driver PCB
The illumination driver PCB shown in Figure 1-2 is controlled and monitored by the controller PCB over a flex
cable. Power can be input to the illumination driver from a bench top supply. The illumination driver provides
reverse bias protection and supplies power to the controller PCB over a separate cable. The illumination driver
PCB regulates the input power to 17 V prior to the illumination driver circuitry. The illumination driver has outputs
for red, green and blue illuminators. These are typically LEDs, but it is possible other illuminators can be used.
Together with the controller PCB, the illuminators are meant to be sequentially pulsed and synchronized with the
operation of the DMD micromirrors. See
Electrical Specifications for input and output specifications of the EVM.
Depending on operating conditions, some parts and surfaces of the PCB can be hot.
CAUTION
Hot surface. Contact might cause burns. Do not touch!
