DLPA2000 - Texas Instruments

DLPA2000 Power Management and LED/Lamp Driver

The DLPA2000 is a dedicated PMIC/RGB LED/lamp driver for the DLP2010 and DLP2010NIR digital micromirror devices (DMD) when used with a DLPC3430, DLPC3435, or DLPC150 digital controller. For reliable operation of these chipsets, it is mandatory to use the DLPA2000. Device Information(1) PART NUMBER PACKAGE BODY SIZE (NOM) DLPA2000 DSBGA (56) 3.28 mm × 3.
