DLPA3005DPFD

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 and up to 32 A 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 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. One 8-bit
programmable buck converter can be used, for
instance, to drive 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 200 mA. These LDOs are
predefined 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 selfprotections, and an analog MUX for routing analog
information to an external ADC.
