Summary
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, operation to 110°C with airflow. For extremely high
vibration environments the case has holes for screw
mounting. Inhibit or open frame mounting provide a high
level of application specific engineering and design-in flex-
ibility.
The IMX 35 series of board mountable 35 Watt DC-DC con-
verters has been designed according to industry require-
ments and standards. The converters are particularly suit-
able for use in mobile or stationary applications in trans-
port, railways, industry, or telecommunication where vari-
able input voltages or high transient voltages are prevalent.
Covering a total input voltage range from 9 V up to 150 V
with 4 different types. The units are available with up to
quadruple outputs (electrically isolated) from 3.3 V up to
60V externally adjustable and with flexible load distribution.
A shut down input allows remote converter on/off. Features
include consistently high efficiency over the entire input
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 basic insulation.
