• Integrated LC EMI filter
• Permanent short circuit protection
• Standard pin out DIL24 9 pins
• Inhibit function
• No optocoupler for high reliability
The MGDM-04 series is a full family of high per-
formance 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 pro-
file 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.

Note * : The ripple output voltage is the periodic AC component imposed on the output voltage, an aperiodic and random component (noise) has also to be considered. This
noise can be reduced by adding an external capacitor (typically 10nF/rated voltage depending on isolation requirement) connected between the pin Gin and the pin Gout
of the converter. This capacitor should be layed-out as close as possible from the converter.
Note ** : For load regulation characteristics from 0% to full load, please see page 6.
