Hi-Rel DC/ DC CONVERTER

MGDM-04 : 4W POWER

Hi-Rel

Grade

Single, Bi & Triple Outputs

Metallic Case - 1.500 VDC Isolation

• 28 Vdc input compliant with MIL-STD-704 D/ E

‘’

• Low profile : 0,3 (7.5mm)

• Nominal power of 4W without derating

• Wide temperature range : -40° C/ +105° C case

• Soft start

• Galvanic isolation 1.500 VDC

• Integrated LC EMI filter

1-General

• Permanent short circuit protection

• Standard pin out DIL24 9 pins

• Inhibit function

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.

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.

• No optocoupler for high reliability

4

All the modules are designed with LC network

filters to minimize reflected input current ripple

and output voltage ripple.

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 (10nF/ rated voltage

c

depending on isolation requirement) connected between Gin and Gout.

EMI Filter module reference : FGDM-2A-50V.

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 :

Pdiss = Pout(1/ h- 1)

determine the maximum ambient temperature :

Ta = 105° C - Rth x Pdiss

where Rth is the thermal resistance from the case to ambient.

4

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

Vo (%)

11-1 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.

11-2 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 mo-

dule 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) :

On/ Off

• A logic pulled low (<0.2V@1mA, referenced to Gi)

on pin 20 disables the converter

• No connection or high impedance on pin 20 enables

the converter.

Command

GI

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’’ Applica-

tion 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 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.

13-2 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.

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.
