An ultra-portable projector can be created by using a DLP chip set comprised of a DLP3010 (.3 720) DMD, a DLPC3433 or DLPC3438 controller, and the DLPA3000 PMIC/LED Driver. The DLPC3433 or DLPC3438 does the digital image processing, the DLPA3000 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 DLPC3433 or DLPC3438. 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 projector. For connecting the DLPC3433 or DLPC3438 to the front-end chip for receiving images, the parallel interface is typically used. While using the parallel interface, I²C should be connected to the front-end chip for inputting commands to the DLPC3433 or DLPC3438.

The DLPA3000 has five built-in buck switching regulators to serve as projector system power supplies. Two of the regulators are fixed to 1.1 V and 1.8 V for powering the DLP chipset. The remaining three buck regulators are available for general purpose use and their voltages are programmable. These three programmable regulators can be used to drive variable-speed fans or to power other projector chips, such as the front-end chip. The only power supply needed at the DLPA3000 input is SYSPWR from an external DC power supply or internal battery. The entire 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.
