8.2.2 Detailed Design Procedure

For a complete DLP system, an optical module or light engine is required that contains the DLP470TP DMD, associated illumination sources, optical elements, and necessary mechanical components.

To ensure reliable operation, the DMD must always be used with two DLPC6421 display controllers and the DLPA3005 PMIC and LED driver. Refer to PCB Design Requirements for TI DLP Pico TRP Digital Micromirror Devices for the DMD board design and manufacturing handling of the DMD sub assemblies.
