The MGDM-150 low input voltage 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. Stan-

dard models are available with ultra wide input

voltage 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-150 low input voltage series include

synchronization load sharing, trim and sense

functions.

The synchronization function allows to synchronize

more than one converter to one frequency or an

external source frequency. The load sharing allows

parallel operation to increase power with a true

N+1.

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 and

overvoltage lock-out, output overvoltage protec-

tion, 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 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

substrate to ensure optimum power dissipation

under harsh environmental conditions.

MGDM-150 Low Input Series

3- Block Diagram

The MGDM-150 low input series DC/DC converter is

based on a

constant

420KHz pulse-width modulated

forward topology designed for

ultra large input

range.

The output voltage is monitored on the secondary

side avoiding the use of optocoupler to optimize

long-term reliability

and provide good immunity

against radiations.

An auxilliary supply is implemented to feed

independently all security functions such as the input

undervoltage lock-out (UVLO), overvoltage lock-out

(OVLO), the output overload protection (OCP), the

output overvoltage protection (OVP) and the ther-

mal protection (OTP).

Hi-Rel

Grade

As this auxilliary power is independent from the main

power supply, the module features an

extreme wide

trim windows from 10% to 110%

of the nominal

output voltage.

The main power transformer designed for more than

150W power is a multi-layer planar transformer which

allows 100% reproductibility for optized module

efficiencies.

The controlled feedback regulation is located at the

secondary side allowing a high regulation bandwidth

and a very fast response to load changes.

Note * : These performances are measured with the sense line connected..

Note ** : It is recommended to mount the converter on a heatsink for this test, see section 10-3 and 10-9 for further details.

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 4 external decoupling capacitors connected between inputs and case and between outputs and case. These capacitance should

be layed-out as close as possible from the converter. Please refer to page 8 for more details.
