Description

The DLPA3005 is a highly-integrated power management IC optimized for DLP® Pico™ Projector systems. The DLPA3005 supports LED projectors up to 16 A per LED, enabled by an integrated high efficiency buck controller. Additionally, the drivers control the RGB switches, supporting the sequencing of R, G, and B LEDs. The DLPA3005 contains five buck converters, two of which are dedicated for DLPC low voltage supplies. Another dedicated regulating supply generates the three timing-critical DC supplies for the DMD: VBIAS, VRST, and VOFS.

The DLPA3005 contains several auxiliary blocks which can be used in a flexible way. This enables a tailor-made Pico Projector system. Three 8-bit programmable buck converters can be used, for instance, to drive rgb projector FANs or to make auxiliary supply lines. General Purpose Buck2 (PWR6) currently supported, others may be available in the future. Two LDOs can be used for a lower-current supply, up to 200 mA. These LDOs are pre-defined to 2.5 V and 3.3 V.

Through the SPI, all blocks of the DLPA3005 can be addressed. Features included are 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.
