DLPA2000 - PMIC/LED Driver for DLP2010 (0.2 WVGA) DMD

The DLPA2000 is a dedicated PMIC/RGB LED/lamp driver for the DLP2010 and DLP2010NIRdigital micromirror devices (DMD) when used with a DLPC3430, DLPC3435, or DLPC150 digitalcontroller. For reliable operation of these chipsets, it is mandatory to use the DLPA2000.
