Series Description
The MGDM-205 low input series is a line of high density wide input range DC/DC power modules designed for aerospace, military and high-end industrial applications where high power density is a critical parameter. 
With 160 W power, this DC/DC converter is particularly suitable for ultra compact power supply design. Standard models are available with ultra wide input voltage range of 9-45 volts. The series include single output voltage of 5 and 12 volts. The MGDM-205 low input series includes, trim and sense functions, and an optional synchronization function.     
The synchronization function allows to synchronize more than one converter together  or to an external source frequency. 
All the modules are designed with LC network filters to minimize reflected input current ripple and output voltage ripple. The modules have totally independant security functions including input undervoltage lock-out, output overvoltage protection, output current limitation protection, and temperature protection. Additionnally a soft-start function allows current limitation and eliminates inrush current during start-up. The design has been carried out with planar transformer and is manufactured in a fully automated process to guarantee high quality. The modules are potted with a state-of-the-art thermal conductive compound and used an insulated metallic substrat to ensure optimum thermal transfert under harsh environmental conditions.
