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.
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.
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.
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.
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
