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.

1. If components are required in tape and reel format suffix order code with -R, e.g. MTU10505MC-R.
2. Calculated using MIL-HDBK-217 FN2 calculation model with nominal input voltage at full load.
3. See ripple & noise characterisation method.
4. Measured after 1 hour continuous operation at nominal VIN full load at the center of each PCB.
All specifications typical at TA=25°C, nominal input voltage and rated output current unless otherwise specified.
