Design Requirements

A Pico projector is created by using a DLP chipset comprised of DLP230KP (.23 HD) DMD, DLPC3434 controller, a LFE5U-85F-7BG381CAMK FPGA, and DLPA2000 PMIC/LED driver. The DLPC3434 does the digital image processing, the DLPA2000 provides the needed analog functions for the projector, and DMD is the display device for producing the projected image.

In addition to the three DLP chips in the chipset, other chips may be needed. At a minimum a flash part is needed to store the software and firmware to control the DLPC3434. In addition, a flash part is needed to store the FPGA program.

The illumination light that is applied to the DMD is typically from red, green, and blue LEDs. These are often contained in three separate packages, but sometimes more than one color of LED die may be in the same package to reduce the overall size of the pico-projector.

The entire pico-projector can be turned on and off by using a single signal called PROJ_ON. When PROJ_ON is high, the projector turns on and begins displaying images. When PROJ_ON is set low, the projector turns off and draws just microamps of current on SYSPWR. When PROJ_ON is set low, the 1.8-V supply can continue to be left at 1.8 V and used by other non-projector sections of the product. If PROJ_ON is low, the DLPA2000 will not draw current on the 1.8-V supply.
