The DLPA3000 is a highly integrated power management IC optimized for DLP Pico Projector systems. It is targeting accessory applications up to several hundreds of lumen and is designed to support a wide variety of high-current LEDs. Functional Block Diagram shows a typical DLP Pico Projector implementation using the DLPA3000.

Part of the projector is the projector module which is an optimized combination of components consisting of for instance DLPA3000, LEDs, DMD, DLPC chip, memory and optional sensors/fan. The front-end chip controls the projector module. More information about the system and projector module configuration can be found in a separate application note.

Within the DLPA3000 several blocks can be distinguished. The blocks are listed below and subsequently discussed in detail:

1. Supply and monitoring: Creates internal supply and reference voltages and has functions such as thermal protection and low battery warning
2. Illumination: Block to control the light. Contains drivers, strobe decoder for the LEDs and power conversion
3. DMD: Generates voltages and their specific timing for the DMD. Contains regulators and DMD/DLPC buck converters
4. Buck converter: General purpose buck converter.
5. Auxilairy LDOs: Fixed voltage LDOs for customer usage
6. Measurement system: Analog front end to measure internal and external signals
7. Digital control: SPI, digital control
