1-General
• 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 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.

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.

8-1 Module Compliance with MIL-STD-461C/D/E Standards
To meet the latest US military standards MIL-STD-461D/E (and also the MIL-STD-461C) requirements and in particular the
conducted noise emission CE102 (and also CE03) requirements, Gaïa Converter can propose a stand-alone ready-to-use EMI
filter module. This EMI filter module has to be used together with a common mode noise capacitance C c (10nF/rated voltage
depending on isolation requirement) connected between Gin and Gout.
EMI Filter module reference : FGDM-2A-50V.
Please consult EMI filter datasheet for further details.

Note * : The upper temperature range depends on configuration, the user must assure a max. case temperature of + 105°C.
The MGDM-04 series operating case temperature must not exceed 105°C. The maximum ambient temperature admissible
for the DC/DC converter corresponding to the maximum operating case temperature of 105°C depends on the ambient
airflow, the mounting/orientation, the cooling features and the power dissipated.
To calculate a maximum admissible ambient temperature the following method can be used. Knowing the maximum case
temparature Tcase = 105°C of the module, the power used Pout and the efficiency h:
• determine the power dissipated by the module Pdiss that should be evacuated :
h - 1)
Pdiss = Pout(1/h
• determine the maximum ambient temperature :
Ta = 105°C - Rth x Pdiss
where Rth is the thermal resistance from the case to ambient.

The previous thermal calculation shows two areas of operation :
• a normal operation area in a free natural ambient convection (grey area in this following graph),
• an area with cooling features (air flow or heatsink) ensuring a maximum case temperature below the maximum
operating case temperature of 105°C (white area in the following graph).

11- Description of Protections
11-1 Output Short Circuit Protection (SCP)
The short circuit protection device protects the module
against short circuit of any duration and restores the module to normal operation when the short circuit is removed.
It operates in «hiccup» mode by testing periodically if an
overload is applied (typically every 200ms recovery time).
The overload detection threshold is typically 200% of maximum current with a detection time lower than 5ms.

11-2 Output Overvoltage Protection (OVP)
The output overvoltage protection device protects external
components against high voltage or possible overvoltages
which can be supplied by the module (i.e in case of internal
failure). It consists of a zener diode clamping the output
voltage; under worst case conditions this zener diode will
short-circuit.
The output voltage protection is not designed to withstand
externally applied output overvoltages to protect the module itself.

12- Description of Functions
12-1 On/Off Function
The control pin 20 (On/Off) can be used for applications
requiring On/Off operation. By using an open collector
command with a transistor Q referenced to the common
terminal (Gi) :
• A logic pulled low (<[email protected], referenced to Gi)
on pin 20 disables the converter
• No connection or high impedance on pin 20 enables
the converter.
On/Off
Command
By releasing the On/Off function, the converter will restart
within the start-up time specifications given in table page 3.
For further details please consult ‘’Logic On/Off’’ Application Note.

13- Application Notes
13-1 Connection of Outputs in Series
Any of the bi output converters can be configured to produce
an output of 10V (+/-5 output models), 24V (+/-12V output models), or 30V (+/-15V output models) by connecting
the load across the output (+) and the output (-) with
either output grounded, and leaving the common pin
floating.

13-2 Connection of Modules in Series
The output of single output units can be connected in
series without any precautions to provide higher output
voltage level.
Nevertheless, GAIA Converter recommends to protect each
individual output by a low power shottky diode rated with
the maximum current of the converter to avoid reverse
polarity at any output.
Reverse polarity may occur at start up if the output voltages do not rise at the same time.

13-3 Connection of Modules in Parallel
Several converters with equal output voltage can be
connected in parallel to increase power. Nevertheless some
cares have to be taken in particular as the output voltage
of each converter is slightly different, when paralleling,
the converter with the highest output voltage will source
the most current.
However the GAIA Converter modules are designed with a
“soft’’ output voltage versus current characteristic. This
causes the output voltage of each converter to automatically
adjust downward as its current increases so each converter
very approximately shares the total output current. It is
important that each converter has approximately the same
impedance between their output and the common load.
