Summary

The IMX 35 series of board mountable 35 Watt DC-DC con-

verters has been designed according to the latest industry

requirements and standards. The converters are particu-

larly suitable for use in mobile or stationary applications in

transport, railways, industry, or telecommunication where

variable input voltages or high transient voltages are preva-

lent.

Covering a total input voltage range from 9 up to 75 V with

2 different types. The units are available with double, triple

and quadruple outputs, electrically isolated, from 3.3 V up

to 60 V externally adjustable and with flexible load distribu-

tion. A shut down input allows remote converter on-off. Fea-

tures include consistently high efficiency over the entire in-

put voltage range, high reliability and excellent dynamic re-

sponse to load and line changes.

The converters are designed and built according to the in-

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

CSA C22.2 No.950-95. LGA, UL and cUL approvals are in

progress. The IMX 35 types provide supplementary insula-

tion. Connected to a secondary circuit the 40 IMX 35 types

provide SELV outputs even if the voltage at the converter

input exceeds the SELV-limit of 60 V DC.

The circuit comprises of two planar magnetics devices and

all components are automatically assembled and solidly

soldered onto a single PCB without any wire connection.

Magnetic feedback ensures maximum reliability and

repeatability in the control loop over all operating condi-

tions. Careful considerations of possible thermal stresses

ensure the absence of hot spots providing long life in envi-

ronments where temperature cycles are a reality. The ther-

mal design without using any potting material allows opera-

tion at full load up to an ambient temperature of 71°C in free

air. For extremely high vibration environments the case has

holes for screw mounting. Various options as e.g. extended

temperature range –40...85°C or an alternative pinout pro-

vide a high level of application specific engineering and de-

sign-in flexibility.
