1-General
The MGDM-20 series is a complete line of high
performance DC/DC power modules designed for
aerospace, military and high-end industrial ap-
plications. These modules use a high frequency
fixed swiching technic at 500KHz providing ex-
cellent reliability, low noise characteristics and
high power density. Standard models are
available with standard input voltage range of
4.5-5.5, 9-36 and 16-40 volts. The series include
single bi and triple output voltage choices of
3,3 , 5, 12, 15 volts.
No external heatsink is required for the MGDM-
20 series to supply 20W 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, and a perma-
nent short circuit protection to ensure efficient
module protection. 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.The modu-
les 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 * : For proper operation the MGDM-20 module requires to install a 22µF chemical or tantalum capacitor accross output terminal.
Note ** : For 9-36V input range, the current is derated at 80% at 9V and increases linearly to full current at 12V.
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 capacitance (typically 10nF/rated voltage depending on isolation requirement) connected between the pin Gin and the
pin Gout of the converter.This capacitance should be layed-out as close as possible from the converter.
