DLPA2000 (ACTIVE)

PMIC/LED Driver for DLP2010 (0.2 WVGA) DMD

 

Recommended alternative parts

  • DLPA2005  - The device has the SAME FUNCTIONALITY as the compared device, but is not pin-for-pin equivalent and may not be parametrically equivalent.   Similar to DLPA2000 but has LED driver current capacity of 2.4A

Description

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.
