The DLPA3085 is a highly integrated power management IC optimized for DLP Pico™ Projector systems. The DLPA3085 supports LED projectors up to 16A per LED and up to 32A for series LEDs, 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 DLPA3085 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 DLPA3085 contains several auxiliary blocks which can be used in a flexible way. This enables a tailor-made Pico Projector system. One 8-bit programmable buck converter can be used, for instance, to drive an RGB projector FAN or to make auxiliary supply line. General purpose buck2 (PWR6) is currently supported. Two LDOs can be used for a lower-current supply, up to 200mA. These LDOs are predefined to 2.5V and 3.3V.
Through the SPI, all blocks of the DLPA3085 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.
