DLPA3000DPFD-PMIC/LED Driver for DLP3010 (0.3 720p) DMD

The DLPA3000 is a highly-integrated power management IC optimized for DLP Pico Projector systems. The device is targeting accessory applications up to several hundreds of lumen.

The DLPA3000 supports LED projectors up to 6 A per LED, enabled by an integrated high efficiency buck converter. On top of that, 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: VBIAS, VRST, and VOFS.

The DLPA3000 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 (not all supported yet) can be used, for example, to drive the projector FANs or to make auxiliary supply lines. Two LDOs can be used for a lower-current supply of up to 200 mA. These LDOs are pre-defined to 2.5 V and 3.3 V.

Through the SPI, all blocks of the DLPA3000 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.
