Summary

The IMX 7 series of board mountable 7 Watt DC-DC con-

verters has been designed according to the latest industry

requirements and standards. The converters are particularly

suitable for use in mobile or stationary applications in trans-

port, railways, industry or telecommunications where vari-

able input voltages or high transient voltages are prevalent.

Covering a total input voltage range from 8.4 V DC up to

150 V DC with four different types the units are available

with single and electrically isolated double outputs allowing

the configuration of output voltages from 3.3 V DC up to

48 V DC externally adjustable, with flexible load distribution

on double output units. An inhibit input allows remote con-

verter on/off.

Features include efficient input and output filtering with un-

surpassed transient and surge protection, low output ripple

and noise, consistently high efficiency over the entire input

voltage range, high reliability as well as excellent dynamic

response to load and line changes.

The converters provide supplementary insulation with

SELV outputs as e.g. required in battery supported sys-

tems where the bus voltage may exceed the SELV limit of

60 V DC. They are designed and built according to the inter-

national safety standards IEC/EN 60950, UL 1950, CAN/

CSA C22.2 No.950-95 and are LGA and UL marked. The

70 IMX 7 and 110 IMX 7 types are CE marked.

The circuit comprises of integrated planar magnetics and

all components are automatically assembled and solidly

soldered onto a single PCB without any wire connections.

Magnetic feedback ensures maximum reliability and re-

peatability in the control loop over all operating conditions.

Careful considerations of possible thermal stresses ensure

the absence of hot spots providing long life in environments

where temperature cycles are a reality. The thermal design

allows operation at full load up to an ambient temperature

of 85°C in free air without using any potting material. For

extremely high vibration environments the case has holes

for screw mounting.

Various options as e.g. extended temperature range

–40...85°C, industrial C pinout or SMD pinout provide a

high level of application specific engineering and design-in

flexibility.
