DLP® PMIC/LED driver for DLP3010 (0.3 720p) DMD

The DLPA3000 is a highlyintegrated

power management IC optimized for

DLP Pico Projector systems. The device is targeting

accessory applications up to several hundreds of

lumens.

The DLPA3000 supports LED projectors

up to 6 A per LED, enabled by an integrated high efficiency buck converter.

Additionally,

the low-ohmic RGB switches support the sequencing of red, green, and blue LEDs. The

DLPA3000 contains five buck converters with two dedicated for DLPC low-voltage

supplies. Another dedicated regulating supply generates the three timing-critical DC

supplies for the DMD: V BIAS, V RST, and V OFS.

The DLPA3000 contains several

auxiliary blocks

that

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 example, to drive the projector

FAN or

to make auxiliary supply lines.

General

purpose buck2 (PWR6) is currently supported. Two LDOs can be used

for a lower-current supply of up to 200 mA. These LDOs are

predefined

to 2.5 V and 3.3 V.
