Hi-Rel

Grade

Single, Bi & Triple Outputs

Metallic Case - 1.500 VDC Isolation

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

• Low profile : 0,33 “ (8.5mm)

• Nominal power of 10 W without derating

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

• High efficiency up to 83 %

• Soft start

• Galvanic isolation 1.500 VDC

• Integrated LC EMI filter

• Permanent short circuit protection

• Parallel operation master/slave

• No optocoupler for high reliability

• RoHS or Leaded process option

The MGDM-10 series is a full family of high perfor-

mance DC/DC low profile power modules designed

for aerospace, military and high-end industrial ap-

plications. These modules use a high frequency

fixed switching technic at 480 KHz providing ex-

cellent 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, +/-15 or +/-24 volts. No external heatsink is

required for the MGDM-10 series to supply 10W

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 out-

put voltage ripple.

The modules include a soft-start, an input

undervoltage lock-out, 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

an excellent thermal conductive compound and

packaged in a metallic case to ensure the module’s

integrity under high temperature conditions.

Note * : For proper operation the MGDM-10 module requires to install a 22µF chemical or tantalum capacitance accross output terminals.

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 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.
