Datasheet
DLPA2005 Power Management and LED/Lamp Driver IC datasheet (Rev. B)
 

Recommended alternative parts

  • DLPA2000  - 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 DLPA2005 but has LED driver current capacity of 650mA

Description

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.
