PRODUCT OVERVIEW
ISOLATION CHARACTERISTICS
Parameter Conditions Min. Typ. Max. Units
The MTU1 series is a new range of miniature
Isolation voltage Flash tested for 1 second 1000 VDC
surface mount, high performance 1W DC-DC
Resistance Viso= 1000VDC 10 G
converters. With a footprint reduction of over 50%
from the previous generation of 1W SMD DC-DC,
GENERAL CHARACTERISTICS
the MTU1 series offers 1W of available output

power over the full industrial temperature range of
MTU1D0305MC 70
-40C to 85C. The MTU1 series is more efcient
3.3V & 5V input, all output types
and offers improved regulation performance for

applications where a wide output voltage variation
12V input, single output types 90
can not be tolerated.
12V intput, dual output types 100
The devices are suitable for all applications where
high volume production is envisaged.
