ABRIDGED DATA SHEET
MAX3601
Laser Driver for Projectors
General Description
The MAX3601 laser driver for pico projectors supports
video imaging with red, blue, and green lasers. Each
output includes two 8-bit digital-to-analog converters
(DACs) with programmable gain and up to 400mA
driving capability per channel. DAC A has a full-scale
current up to 320mA, while DAC B has full-scale current
up to 80mA. All three channels can be combined into a
single channel with up to 1.2A drive capability.
Maxim’s patented technology allows pulsed current to
operate lasers efficiently while reducing speckle. This
feature operates from the video data clock. The driver
is available in a 3.0mm x 3.5mm, 42-bump wafer-level
package for commercial applications and a 5mm x 5mm,
40-pin TQFN package for industrial and automotive
applications.
