DLPA2005 - High Current PMIC/LED Driver for DLP2010 DMD and DLP2010NIR (0.2 WVGA) DMD

DLPA2005 is a dedicated PMIC/RGB LED/Lamp driver for the DLP2010, DLP2010NIR and DLP3010 Digital Micromirror Devices (DMD) when used with a DLPC3430, DLPC3433, DLPC3435, DLCP3438, or DLPC150 digital controller. For reliable operation of these chipsets it is mandatory to use a DLPA2000 or DLPA2005.
