The DLPA4000 device is a highly-integrated power management driver. It is optimized for DLP® LED projector systems. The DLPA4000 supports projectors up to 32 A per LED with high-side pump functionality. An integrated, high-efficiency buck controller energizes the device. The drivers control switches support the sequencing of R, G, and B LEDs. The device contains five buck converters, two of which are dedicated for the DLPC4422 controller low-voltage supply. Another dedicated regulated supply energizes the DLPA200 DMD micromirror driver and the three timing critical DC supplies for the DMD: VBIAS, VRST, and VOFS.

The DLPA4000 device contains several auxiliary blocks. These blocks allow flexibility in LED projector system design. An 8-bit programmable buck converter can drive an RGB projector fan or make an auxiliary supply line. Two LDOs can generate a lower-current supply, up to 200 mA. These LDOs are specified to operate at 2.5 V and 3.3 V.

The serial protocol interface (SPI) addresses all blocks of the DLPA4000 device. These addressable features include: the generation of the system reset, power sequencing, input signals for sequentially selecting the active LED, IC self-protections, and an analog MUX for routing analog information to an external ADC.
