nnThe MGDM-35 wide input series is a full family ofDC/DC power modules designed for aerospace,military and high-end industrial applications.
These modules use a high frequency fixed swiching
technic at 250KHz providing excellent reliability,
low noise characteristics and high power density.
Standard models are available with wide input
voltage range of 9-36, and 16-75. The serie
includes single, bi and triple output voltage choices
of 3.3, 5, 12, 15 volts.
No external heatsink is required for the
MGDM-35 series to supply 35W output power over
the full temperature range.
All the modules are designed with LC network
filters to minimize reflected input current ripple
and output voltage ripple .
The modules include a soft-start, an inputundervoltage lock-out, a permanent short cir-
cuit protection and an output overvoltage pro-
tection to ensure efficient module protections.
The soft-start allows current limitation and
eliminates inrush current during start-up. The
short circuit protection completely protects the
modules against short-circuits of any duration
by a shut-down and restores to normal when
the overload is removed.
The design has been carried out with surface
mount components and is manufactured in a
fully automated process to guarantee high
quality. Each module is tested with a GAIA
Converter automated test equipment. nn4 nnSingle output model: MGDS-35-
