7 Detailed Description

7.1 Overview

The DLPA2000 is a power management and LED driver IC optimized for DLP video and data display systems

and meant for use in either embedded or accessory projector applications. DLPA2000 is part of the chipset

comprising of either DLP2010 (.2 WVGA) DMD and DLPC3430/DLPC3435 controller or the DLP2010NIR (.2

WVGA NIR) DMD and DLPC150 controller. The DLPA2000 contains a complete LED driver including high

efficiency power convertors. The DLPA2000 can supply up to 750 mA per LED. Integrated high-current switches

are included for sequentially selecting R, G, and B LEDs. The DLPA2000 also contains three regulated DC

supplies for the DMD reset circuitry: VBIAS, VRST and VOFS, as well as a regulated DC supply of 1.1 V and a

load switch for the 1.8 V to support the DLPC3430 or DLPC3435 controller. The DLPA2000 also contains a

motor driver which can be used to drive the focus lens motor. The DLPA2000 has a SPI used for setting the

configuration. Using SPI, currents can be set independently for each LED with 10-bit resolution. Other 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.
