Typical Application Setup Using DLPA3000

A common application when using DLPA3000 is to use it with a DLP3010 DMD and DLPC3433/DLPC3438 controller for creating a small, ultra-portable projector. The DLPC3433/DLPC3438 in the projector typically receives images from a PC or video player using HDMI or VGA analog, as shown in Figure 27. Card readers and Wi-Fi can also be used to receive images if the appropriate peripheral chips are added. The DLPA3000 provides power supply sequencing and control of the RGB LED currents as required by the application.
