• Low profile : 0,33’’ (8.5mm)
• Wide input range and high transient compliance

• RoHS process
The MGDI-04 wide input series is a full family of
DC/DC power modules designed for use in
distributed power architecture where variable
input voltage and transient are prevalent making
them ideal particularly for transportation,
railways or high-end industrial applications. These
modules use a high frequency fixed swiching
technic at 480 KHz providing excellent reliability,
low noise characteristics, high power density and
low profile package. Standard models are
available with wide input voltage range of 9-36,
16-40 and 36-140 volts, with high transient levels.
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 MGDI-
04 series to supply 4W output power over the
case temperature range of -40°C up to 95°C.
The MGDI-04 series is designed in conformity
with safety standards EN60950 and UL1950.
All the modules are designed with LC network
filters to minimize reflected input current ripple
and output voltage ripple according to EN55022
and FCC Part 15J standard.
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
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.

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 contact factory.
Note ***: The MGDSI-04-Q-B module output voltage is ranging from 3.25Vdc at full load to 3.55 Vdc at quarter load..
