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.
