PRODUCT OVERVIEW

The MTU1 series is a new range of miniature

surface mount, high performance 1W DC/DC

converters. With a footprint reduction of over 50%

from the previous generation of 1W SMD DC/DC,

the MTU1 series offers 1W of available output

power over the full industrial temperature range of

-40ºC to 85ºC. The MTU1 series is more efficient

and offers improved regulation performance for

applications where a wide output voltage variation

can not be tolerated.

The devices are suitable for all applications where

high volume production is envisaged.
