Description
mechanical design the units withstand an extremely high level
of shock and vibrations. 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.
The IMX4 Series of board-mountable, 4 watt dc-dc converters has
been designed according to the latest industry requirements and
standards. The converters are particularly suitable for use in mobile
or stationary applications in transport, industry or telecom where
variable input voltages or high transient voltages are prevalent.
Covering a total input voltage range from 8.4 V DC up to 121 V DC
with three different types the units are available with single and dual
outputs from 3.3 up to 24 V DC with flexible load distribution on
dual outputs. Features include efficient input and output filtering
with unsurpassed 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 to 85°C, or K-pinout, an alternative to the standard
industrial pinout, provide a high level of application specific
engineering and design-in flexibility.
The converters exhibit basic insulation and are designed and built
according to the international safety standards IEC/EN 60950, UL
1950, CAN/CSA C22.2 No.950-95 and are LGA and UL marked.
70IMX4 types have are also CE marked.
A special feature is their small case size, DIL 24 with only 8.5 mm
profile. The circuit comprises integrated planar magnetics and all
components are automatically assembled and solidly soldered
onto a single PCB without any wire connections. Thanks to the rigid

The IMX4 dc-dc modules are feedback controlled flyback
converters using current mode PWM (Pulse Width Modulation).
The close magnetic coupling provided by the planar
construction ensures very good regulation and allows for
flexible load distribution on dual output types.
The converter input is protected against transients by means of a
suppressor diode.
The output voltage is monitored by a separate transformer winding
close to the secondary windings and fed back to the control circuit.
Current limitation is provided by the primary circuit, thus limiting

Inrush Current
Electromagnetic emission requirements according to table
Input data can be achieved by adding an external capacitor
as close as possible to the input terminals.
The inrush current has been kept as low as possible by
choosing a very small input capacitance. A series resistor

Input Transient Voltage Protection
In many applications transient voltages on the input of the
converter are always a possibility. These may be caused
for example by short circuits between Vi+ and Vi– where
the network inductance may cause high energy pulses.
To withstand the 150 V transient according to 19 Pfl 1,
applicable for 40IMX4 types, the same external circuitry
with similar components as for IEC/EN 61000-4-5, level 2
compliance can be used.
04036
In order to protect the converter a large transient voltage
suppressor has been fitted to the input of the IMX4 types.

Thermal Considerations
Output Overvoltage Protection
If a converter, mounted on a PCB, is located in free, quasi-
stationary air (convection cooling) at the indicated maximum
The outputs of the IMX4 converters are protected against
overvoltages by Zener diodes. In the event of an overvoltage
on the output, the unit will shut-down and attempt to restart
automatically. The main purpose of this feature is to protect
against possible overvoltages which could occur due to a
failure in the feedback control circuit. The units are not
designed to withstand external overvoltages applied to the
outputs.
ambient temperature TA
(see table: Temperature
max
specifications) and is operated at its nominal input voltage and
output power, the case temperature TC measured at the:
Measuring point of case temperature TC (see: Mechanical Data)
will approach the indicated value TC max after the warm-up phase.
However, the relationship between TA and TC depends heavily on
the conditions of operation and integration into a system. The
thermal conditions are influenced by input voltage, output
current, airflow, temperature of surrounding components and
surfaces and the properties of the printed circuit board. TA max is
therefore only an indicative value and under practical operating
conditions, the ambient temperature TA may be higher or lower
than this value.
Connection in Series
The outputs of single or dual output units can be connected in
series without any precautions, taking into consideration that
the highest output voltage should remain below 60 V for SELV
operation.
Connection in Parallel
Caution: The case temperature TC measured at the Measuring
point of case temperature TC (see: Mechanical Data) may under
no circumstances exceed the specified maximum value. The
installer must ensure that under all operating conditions TC
remains within the limits stated in the table: Temperature
specifications.
Several converters with equal output voltage can be
connected in parallel and will share their output current quite
equally. However, this may cause start-up problems at initial
start-up, and is only recommended in applications where one
converter is able to deliver the full load current, e.g, in true
redundant systems.
Short Circuit Behavior
Typical Performance Curves
The current limit characteristic shuts down the converter whenever
a short circuit is applied to its output. It acts self-protecting and
automatically recovers after removal of the overload condition.

Safety and Installation Instructions
Installation Instruction
Safety of Operator Accessible Output Circuits
If the output circuit of a dc-dc converter is operator
accessible, it shall be an SELV circuit according to IEC/EN
60950 related safety standards
Installation of the dc-dc converters must strictly follow the national
safety regulations in compliance with the enclosure, mounting,
creepage, clearance, casualty, markings and segregation
requirements of the end-use application.
The insulation concept table on next page shows some
possible installation configurations, compliance with
which causes the output circuit of the dc-dc converter to be
an SELV circuit according to IEC/EN 60950 up to a
configured output voltage (sum of nominal voltages if in
series or +/– configuration) of 48 V.
Connection to the system shall be made via a printed circuit board
according to: Mechanical Data.
The units should be connected to a secondary circuit.
Check for hazardous voltages before altering any connections.
Do not open the module.
However, it is the sole responsibility of the installer to
ensure the compliance with the relevant and applicable
safety regulations. More information is given in: Technical
Information: Safety.
Ensure that a unit failure (e.g., by an internal short-circuit) does
not result in a hazardous condition. See also: Safety of operator
accessible output circuit.
Standards and Approvals
Table 11: Pin allocation for standard industrial pinout and
option Z
All dc-dc converters are UL recognized according to UL
1950, UL recognized for Canada to CAN/CSA C22.2 No.
950-95 and LGA approved to IEC/EN 60950 standards.

To prevent excessive current flowing through the input supply line
in case of a short-circuit across the converter input an external fuse
should be installed in a non earthed input supply line. We
recommend a fast acting fuse F1A for 20IMX4, F0.5A for 40IMX4
and F0.315A for 70IMX4 types.

1 The front end output voltage should match the specified input voltage range of the dc-dc converter.
2 The earth connection has to be provided by the installer according to the relevant safety standard, e.g.IEC/EN 60950.
3 The installer shall provide an approved fuse (type with the lowest rating suitable for the application) in a non-earthed input line directly at
the input of the dc-dc converter (see fig.: Schematic safety concept). For UL’s purpose, the fuse needs to be UL-listed. See also: Input
Fuse.
4 Each suppressor diode should be dimensioned in such a way, that in the case of an insulation fault the diode is able to limit the output
voltage to SELV (<60 V) until the input fuse blows (see fig.: Schematic safety concept).
5 Has to be insulated from earth by double or reinforced insulation according to the relevant safety standard, based on the maximum output
voltage from the front end.
