1-General
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 MGDI-10 series is a full family of DC/DC
power modules designed for use in distributed
power architecture and are particularly suitable
for mobile or ground fixed applications in
transportation, industry and télécommunication
areas. These modules use a high frequency fixed
switching technic at 480 KHz providing excellent
reliability, low noise characteristics, high power
density and a low profile package. Standard
models are available with nominal input volta-
ges as 5, 12, or 24 volts in range of 4,5-5,5 or
18-36 volts. The series include single and bi
output voltage choices of 3,3, 5, 12, 15, +/-5,
+/-12 or +/-15 volts.
The modules include a soft-start, an input
undervoltage lock-out, a permanent short cir-
cuit protection and an output overvoltage pro-
tection 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.
5
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.
No external heatsink is required for the MGDI-
10 series to supply 10W output power over the
case temperature range of -40°C up to 95°C.
The MGDI-10 series is designed in conformity
with safety standards EN60950 and UL1950.

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 * : The upper temperature range depends on configuration, the user must assure a max. case temperature of + 95°C.
The MGDI-10 series operating case temperature must not exceed 95°C. The maximum ambient temperature admissible for
the DC/DC converter corresponding to the maximum operating case temperature of 95°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 = 95°C of the module, the power used Pout and the efficiency η :
• determine the power dissipated by the module Pdiss that should be evacuated :
Pdiss = Pout(1/η - 1)
• determine the maximum ambient temperature :
Ta = 95°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 95°C (white area in the following graph).

11-1 Input Undervoltage Lock-out (UVLO)

The input undervoltage lock-out protection device turns-
on and turns-off the output voltage when the input bus

is no hysteresis cycle at turn-on and turn-off.

11-2 Output Short Circuit Protection (SCP)
100
The short circuit protection device protects the module
against short circuit of any duration and restores the mo-
dule 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 maxi-
mum current with a detection time lower than 5ms.

11-3 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 mo-
dule itself.

12- Application Notes
12-1 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 out-
put 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.

12-2 Connection of Modules in Series
VI
Vo
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 volta-
ges do not rise at the same time.

12-3 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.
