The MGDM-04 series is a full family of high performance and low profile DC/DC power modules
designed for aerospace, military and high-end
industrial applications. These modules use a high
frequency fixed switching technic at 480KHz
providing excellent reliability, low noise
characteristics, high power density and a low profile package. Standard models are available with
nominal input voltages as 5, 12 or 28 volts in
range of 4,5-5,5 , 9-36 or 16-40 volts. The series
include single, bi and triple output voltage choices
of 3.3, 5, 12, 15, +/-5, +/-12 or +/-15 volts. No
external heatsink is required for the MGDM-04
series to supply 4W output power over the case
temperature range of -40°C up to 105°C.
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, a permanent
short circuit protection and an output overvoltage
protection 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
module 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 and burned in with a GAIA
Converter automated test equipment before and
after encapsulation. The modules are potted with
a bi-component thermal conductive compound and
packaged in a metallic case to ensure the module’s
integrity under high environmental conditions.
