1-General

nnThe 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.
All the modules are designed with LC network
filters to minimize reflected input current rippleand output voltage ripple.The modules have totally independant securityfunctions including input undervoltage lock-out,
output overvoltage protection, output currentlimitation protection, and temperature protec-tion. Additionnally a soft-start function allowscurrent limitation and eliminates inrush currentduring 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. nn4 nn
