Description
60950 and approved by TÜV, UL, and cUL. 70IMX4 models are
also CE-marked.
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.
A special feature is their small case size, DIL 24 with only
8.5 mm profile. The circuit is comprised of integrated planar
magnetics, and all components are automatically assembled
and solidly soldered onto a single PCB without any wire
connections. Thanks to the rigid mechanical design the
converters 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.
Covering a total input voltage range from 8.4 VDC up to
121 VDC with three different types, the converters are
available with single and dual outputs from 3.3 up to 24 VDC
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.
Several options as open-frame or an alternative 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

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
the total output current (Io nom for the single- and the sum of
Io1 nom and Io2 nom for the dual-output models).

The close magnetic coupling provided by the planar
construction ensures very good regulation and allows for

Input Transient Voltage Protection
Fuse and Reverse Polarity Protection
In many applications transient voltages on the converter input
are always possible. These may be caused for example by
short circuits between Vi+ and Vi–, where the network
inductance may generate high energy pulses.
A suppressor diode on the input also protects against reverse
polarity input voltage. An external fast fuse is required to limit
this reverse current:
Table 6: External input fuse
To protect the converter a large transient voltage suppressor is
fitted to the input, see table below.

If transients generating currents above the peak pulse current
IPP are possible, an external limiting network such as the circuit
shown in figure 8 is recommended. It provides compliance with
transients according to IEC/EN 61000-4-5, level 2. The compo-
nents are specified in table 5.
If 40IMX4 models should withstand 150 V transients according
to 19Pfl1, the same external circuitry with similar components
shown in figure 8 can be used.

4-Watt DC-DC Converters
However, this may cause start-up problems and is only
recommended in applications, where one converter is able to
deliver the full load current, e.g., in true redundant systems.
Thermal Considerations
If a converter, mounted on a PCB, is located in free, quasi-
stationary air (convection cooling) at the maximum ambient
temperature TA max (see table: Temperature specifications)
and is operated at 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 depend on 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.

Caution: The case temperature TC measured at the measuring

circumstances exceed the specified maximum. The installer must

limits stated in the table: Temperature Specifications.

Output Overvoltage Protection
16.5
The outputs are protected against overvoltages by Zener
diodes. In the event of an overvoltage, the converter 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
converters are not designed to withstand external overvoltages
applied to the outputs.

The outputs of single or dual-output models can be connected

Safety and Installation Instructions
Connection to the system shall be made via a printed circuit
board see Mechanical Data.
Installation Instruction
The converters should be connected to a secondary circuit.
Do not open the converter.
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.
Ensure that a converter failure does not result in a hazardous
condition.

To prevent excessive current flowing through the input lines in
case of a short-circuit, an external fuse specified in table 6 should
be installed in the non-earthed input supply line.

Description of Options
Standards and Approvals
The converters are approved by UL and TÜV according to UL
60950, CAN/CSA C22.2 No. 950-95 and IEC/EN 60950-1:2000.
Option K: Alternative Pinout.
This pinout is compatible with other converters on the market,
for instance with the IPS3 series.
The converters have been evaluated for:
• Building in
• Basic insulation input to output, based on their maximum
input voltage
• Pollution degree 2 environment
• Connecting the input to a secondary circuit, which is subject
to a maximum transient rating of 1500 V for 20IMX4 and
40IMX4, 2000 V for 70IMX4 models.
Option Z: Open Frame
For applications, where the protection of the case is not neces-
sary or in the case that the motherboard should be cleaned and
lacquered with the converter fitted.
The converters are subject to manufacturing surveillance in
accordance with the above mentioned standards.
NUCLEAR AND MEDICAL APPLICATIONS - Power-One products are not designed, intended for use in, or authorized for use as critical
components in life support systems, equipment used in hazardous environments, or nuclear control systems without the express written
consent of the respective divisional president of Power-One, Inc.
TECHNICAL REVISIONS - The appearance of products, including safety agency certifications pictured on labels, may change depending
on the date manufactured. Specifications are subject to change without notice.

IMX4 DC-DC Series Data Sheet
4-Watt DC-DC Converters
EC Declaration of Conformity
We
Power-One AG
Ackerstrasse 56, CH-8610 Uster
declare under our sole responsibility that IMX4 series DC-DC converters carrying the CE-
mark are in conformity with the provisions of the Low Voltage Directive (LVD) 73/23/EEC of
the European Communities.
Conformity with the directives is presumed by conformity with the following harmonised
standards:
• EN 61204:1995 (= IEC 61204:1993, modified)
Low-voltage power supply devices, DC output - Performance characteristics
and safety requirements
• EN 60950-1:2000 (= IEC 60950-1:2000)
Safety of information technology equipment.
The installation instructions given in the corresponding data sheet describe correct installation
leading to the presumption of conformity of the end product with the LVD. All IMX4 DC-DC
converters are components, intended exclusively for inclusion within other equipment by an
industrial assembly operation or by professional installers. They must not be operated as
standalone products.
Hence conformity with the Electromagnetic Compatibility Directive 89/336/EEC (EMC Directive)
needs not to be declared. Nevertheless, guidance is provided in the data sheets on how
conformity of the end product with EMC standards under the responsibility of the installer can
be achieved, from which conformity with the EMC Directive can be presumed.
