Description
1 110IMY15
models
The IMX15, IMS15, and IMY15 Series of board mountable 15-
Watt DC-DC converters have been designed according to the
latest industry requirements and standards. The converters
are particularly suitable for use in mobile or stationary
applications in transport, railways, industry, or telecommu-
nications, where variable input voltages or high transient
voltages are prevalent.
input exceeds the SELV-limit of 60 VDC. The 110IMY15
models provide double insulation and are CE marked. They
may be connected to a rectified 110 VAC source without any
further isolation barrier.
Covering a total input voltage range from 8.4 up to 150 V with
different models, the converters are available with single and
electrically-isolated double outputs from 3.3 up to 48 V,
externally adjustable, with flexible load distribution on double-
output models. A shutdown input allows for remote on/off.
Features include efficient input and output filtering and
consistently high efficiency over the entire input voltage range,
high reliability, and excellent dynamic response to load and
line changes.
The converters have been approved by CSA. 20IMS/20IMX15
and 40IMS/40IMX15 models provide supplementary in-
sulation. Connected to a secondary circuit, these models
provide SELV outputs, even if the bus voltage at the converter
The circuitry is comprised of integrated planar magnetics. 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 conditions. Careful con-
sideration of possible thermal stress ensures the absence of
hot spots providing long life in environments, where
temperature cycles are frequent. 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.

RoHS-Compliant Models
The type designation of RoHS-compliant models (compliant for the restriction of all six substances) for the IMX/IMY15 Series
ends with "G".
However, in single-output models with 3.3 V or 5.1 V output an extra hyphen (-) is added after the existing "G", which already
signifies a synchronous rectifier. This is an exception to Power-One's normal nomenclature to identify this type of product, since
G is already used to designate products for higher output current fitted with a synchronous rectifier. As an example
– 20IMX15-05-8R-G means a standard version with RoHS compliance for all six substances.
– 20IMX15-05-8RG means a synchronous rectifier version which is not RoHS-compliant.
– 20IMX15-05-8RG-G means a synchronous rectifier version and with RoHS compliance for all six substances.
– 20IMX15-05-05-8RG means a double-output model with RoHS compliance for all six substances
– 110IMY15-24-24-8RG means a double-output model with RoHS compliance for all six substances.

Functional Description
03089
The IMX15/IMS15/IMY15 Series of DC-DC converters are
magnetic feedback-controlled flyback converters using current
mode PWM (Pulse Width Modulation). The -05- and -0503-
output voltage models, as well as all double-output models
fitted with option R, exhibit an active magnetic feedback loop
via a pulse transformer, resulting in very tight regulation of the
output voltage (see the block diagrams). The output voltages
of these models can be adjusted via the R input. The R input
is referenced to the secondary side and allows for
programming the output voltages in the range of
approximately 80 to 105% of Vo nom, using either an external
resistor or an external voltage source.

Several single-output models with 3.3 or 5.1 V output exhibit a
synchronos rectifier to improve the efficiency.
R
The voltage regulation on the double-output models without
option R is achieved with a passive transformer feedback
from the main transformer (see fig. 3). The output voltages
can be adjusted via the Trim input. The Trim input is
referenced to the primary side and allows for programming
the output voltage in the range 100 to 105% of Vo nom via an
external resistor or within 75 to 105% using an external
voltage source. The load regulation output characteristic
allows for paralleling of one or more double-output models
with equal output voltage.

Thermal Considerations
Short Circuit Behaviour
If a converter, mounted on a PCB, is located in free, quasi-
stationary air (convection cooling) at the indicated maximum
ambient temperature TA max (see table Temperature
specifications) and is operated at its nominal input voltage and
output power, the case temperature 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.
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 (hiccup mode).
Parallel and Series Connection

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.

Both outputs of the same converter with equal voltage (e.g. 5 V
/ 5 V) can be connected in parallel and will share their output
currents equally. Parallel operation of single or double
outputs of two or more converters with the same output
voltage may cause start-up problems at initial start-up. This is
only advisable in applications, where one converter is able to
deliver the full load current as, for example, required in true
redundant systems.

used, connect it in parallel to the 1st output.
The converters are protected from possible overheating by
means of an internal temperature monitoring circuit. It shuts
down the converter above the internal temperature limit, and
attempts to automatically restart in short intervals. This feature
helps protect against excessive internal temperatures, which
could occur during heavy overload conditions.
Typical Performance Curves

º
– TA = 25 C, unless TC is specified.
– Shutdown pin left open-circuit.
– Trim or R input not connected.
V
Output Overvoltage Protection
05166a
5.5
The output of single-output models as well as -0503- and -05-
05-models are protected against overvoltage by a second
control loop. In the event of an overvoltage on one of the
outputs, the converter will shut down and attempt to restart in
short intervals.
Doublel-output models (except -0503- and -05-05-models) are
protected against overvoltage by a Zener diode across the
second output. Under worst case conditions the Zener diode
will become a short circuit. Since with double-output models
both outputs track each other, the protection diode is only
provided in one of the outputs. The main purpose of this
feature is to protect against possible overvoltage, which could
occur due to a failure in the control logic. This protection circuit
is not designed to withstand externally applied overvoltages.

resistor Rext is possible within 100 to 105% of Vo nom. Rext
should be connected between the Trim pin and Vi–.
Connection of Rext to Vi+ may damage the converter. The
table below indicates suitable resistor values for typical
output voltages under nominal conditions (Vi nom, Io = 0.5
Io nom) with either parallel-connected outputs or equal-load
conditions on both outputs.

Railway Applications
To comply with railway standards, all components are coated
with a protective lacquer (except option Z).
Protection Degree and Cleaning Liquids

The protection degree of the converters is IP 40, except open-
frame models (option Z).

13
In order to avoid possible damage, any penetration of
cleaning fluids should be prevented, since the power
supplies are not hermetical sealed.
However, open-frame models (option Z) leave the factory
unlacquered; they may be lacquered by the customer, for
instance together with the mother board. Cleaning agents are
not permitted – except washing at room temperature with
isopropyl alcohol. If necessary, the mother board must be
cleaned, before fitting the open-frame converter.

Installation Instructions
Isolation
Installation 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 electric strength test is performed in the factory as routine
test in accordance with EN 50116 and IEC/EN 60950, and
should not be repeated in the field. Power-One will not honor
any warranty claims resulting from electric strength field tests.
Connection to the system shall be made via a printed circuit
board with hole diameters of 1.4 mm ±0.1 mm for the pins.
