Summary

The IMX 15 and IMY 15 series of board mountable 15 Watt

DC-DC converters has been designed according to the lat-

est industry requirements and standards. The converters

are particularly suitable for use in mobile or stationary appli-

cations in transport, railways, industry, or telecommunica-

tion where variable input voltages or high transient voltages

are prevalent.

Covering a total input voltage range from 8.4 up to 150 V

with 3 different types, the units are available with single,

dual and electrically isolated double outputs from 3.3 up to

48 V externally adjustable, with flexible load distribution on

dual and double output units. A shut down input allows re-

mote converter on-off. Features include consistently high

efficiency over the entire input voltage range, high reliability

and excellent dynamic response 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 20 IMX 15 and 40 IMX 15 types provide sup-

plementary insulation. Connected to a secondary circuit the

40 IMX 15 types provide SELV outputs even if the bus volt-

age at the converter input exceeds the SELV-limit of

60 V DC. The 110 IMY 15 types provide double insulation

and are CE marked. They may be connected to e.g. a recti-

fied 110 V AC source without any further isolation barrier.

The circuit comprises of integrated planar magnetics and

all components are automatically assembled and solidly

soldered onto a single PCB without any wire connection.

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 71°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 tem-

perature range –40...85°C or an alternative pinout provide

a high level of application specific engineering and design-

in flexibility.
