DLPA3005DPFDR

The DLPA3005 is a highly integrated power management IC optimized for DLP Pico Projector systems. It targets
accessory applications up to several hundreds of lumen and is designed to support a wide variety of high-current
LEDs. Section 7.2 shows a typical DLP Pico Projector implementation using the DLPA3005.
Part of the projector is the projector module, which is an optimized combination of components consisting of,
for instance, DLPA3005, LEDs, DMD, DLPC chip, memory, and optional sensors and 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 DLPA3005, several blocks can be distinguished. The blocks are listed below and subsequently
discussed in detail:
• Supply and monitoring: Creates internal supply and reference voltages and has functions such as thermal
protection
• Illumination: Block to control the light. Contains drivers, strobe decoder for the LEDs and power conversion
• External Power FETs: Capable for 16 A
• DMD: Generates voltages and their specific timing for the DMD. Contains regulators and DMD/DLPC buck
converters
• Buck converter: General purpose buck converter
• Auxiliary LDOs: Fixed voltage LDOs for customer usage
• Measurement system: Analog front end to measure internal and external signals
• Digital control: SPI interface, digital control
