Hi-Rel DC/DC CONVERTER  
MGDM-75 : 75W POWER  
Hi-Rel  
Grade  
5:1 Ultra Wide Input  
Single Output  
Metallic case - 1.500 VDC Isolation  
• Ultra wide input range 16-80 Vdc, 9-45 Vdc  
• 28Vdc input compliant with MIL-STD-704A/D/F  
• Industry standard quarter brick package  
• Power up to 75 W  
• Wide temperature range : -40°C/+ 105° baseplate  
• High efficiency (typ. 86%-90%)  
• Soft start  
1-General  
• Galvanic isolation 1.500 VDC  
• Integrated LC EMI filter  
filters to minimize reflected input current ripple  
and output voltage ripple.  
The MGDM-75 series is a complete line of high  
density wide input range DC/DC power modules  
designed for aerospace, military and high-end  
industrial applications. These modules use a  
patented fixed switching topology at 420 KHz  
providing ultra wide input range, low noise  
characteristics and high power density. Standard  
models are available with ultra wide input vol-  
tage range of 9-45, 16-80 volts. The series  
include single output voltage choices of 3.3, 5,  
12, 15, 24, 28 volts.  
The MGDM-75 series include synchronization, trim  
and sense functions.  
The synchronization function allows to synchronize  
more than one converter to one frequency or an  
external source frequency.  
• Synchronizable  
The modules have totally independant security  
functions including input undervoltage lock-out,  
output overvoltage protection, output current  
limitation protection, and temperature protec-  
tion. Additionnally a soft-start function allows  
current limitation and eliminates inrush current  
during start-up.  
The design has been carried out with surface  
mount components, planar transformer and is  
manufactured in a fully automated process to  
guarantee high quality. The modules are potted  
with a bi-component thermal conductive  
compound and used an insulated metallic subs-  
trat to ensure optimum power dissipation under  
harsh environmental conditions.  
• Fully protected by independant security  
• Under & overvoltage lock-out  
• Overvoltage protection  
• Current limitation protection  
• Overtemperature protection  
• No optocoupler for high reliability
