Описание

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.

High Efficiency RGB LED/Lamp Driver With Buck-
Boost DC-to-DC Converter, DMD Supplies, DPP
Core Supply, 1.8-V Load Switch, and
Measurement System in a Small Chip-Scale
Package
Three Low-Impedance (30 mΩ Typical at 27°C)
MOSFET Switches for Channel Selection
Independent, 10-Bit Current Control per Channel
2.4-A Max LED Current for DLPA2005 Embedded
