Description

The IMX15 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

telecommunication where variable input voltages or high

transient voltages are prevalent.

40IMX15 provide supplementary insulation. Connected to

a secondary circuit the 40IMX15 models provide SELV

outputs, even if the bus voltage at the converter input ex-

ceeds the SELV-limit of 60 VDC. The 110IMY15 models

provide double insulation and are CE marked. They may

be connected for example 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 3 different models, the units are available with

single, dual and electrically-isolated double outputs from

3.3 up to 48 V externally adjustable, with flexible load

distribution on dual and double output units. 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 response to

load and line changes.

The circuit comprises of integrated planar magnetics 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

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.

The converters are designed and built according to the

international safety standards IEC/EN/UL60950 and ap-

proved by TÜV, UL and cUL. The models 20IMX15 and

RoHS-Compliant Models

The type designation of RoHS-compliant models of the IMX/IMY15 series ends with "G". In this series an extra dash (-) is

added after the existing "G", which already signifies a synchronous rectifier at the output. This is an exception to Power-

One's normal nomenclature to identify RoHS-compliant products, 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

– 20IMX15-05-8RG means a synchronous rectifier version without RoHS compliance

– 20IMX15-05-8RG-G means a synchronous rectifier version with RoHS compliance.

Please ask Power-One for availability of RoHS-compliant models.

15-Watt DC-DC Converters

Functional Description

03089

The IMX/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 feature an active

magnetic feedback loop via a pulse transformer, which

results in very tight regulation of the output voltage (see

the block diagrams). The output voltages of these

versions can be adjusted via the R input. The R input is

referenced to the secondary side and allows for

programming of the output voltages in the range of

approximately 80 to 105% of V_{o nom}using either an

external resistor or an external voltage source.

The voltage regulation on the dual and double output

models without option R is achieved with a passive

transformer feedback from the main transformer (see

fig. 3: Block diagram of double output models). The

output voltages can be adjusted via the Trim input. The

Trim input is referenced to the primary side of the

converter and allows for programming of the output

voltages in the range 100 to 105% of V_{o 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 several

double output units with equal output voltages.

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 T_{A max}(see table:

Temperature specifications) and is operated at its

nominal input voltage and output power, the case

temperature T_Cmeasured at the Measuring point of

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).

Connection in Series

case temperature T_C(see: Mechanical Data) will The outputs of one or several single or double output units

approach the indicated value T_{C max}after the warm-up can be connected in series without any precautions, taking

phase. However, the relationship between T_Aand T_Cinto consideration that the highest output voltage should

depends heavily on the conditions of operation and remain below 42 V to ensure that the output remains SELV.

integration into a system. The thermal conditions are

Connection in Parallel

influenced by input voltage, output current, airflow,

Double outputs of the same converter with equal output

voltage (e.g., 5 V / 5 V) can be put in parallel and will share

their output currents almost 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.

temperature of surrounding components and surfaces

and the properties of the printed circuit board. T_{A max}is

therefore only an indicative value and under practical

operating conditions, the ambient temperature T_Amay

be higher or lower than this value.

Caution: The case temperature T_Cmeasured at the

measuring point of case temperature T_C(see: Mechanical

Data) may under no circumstances exceed the specified

maximum value. The installer must ensure that under all

operating conditions T_Cremains within the limits stated in

the table: Temperature specifications.

Typical Performance Curves

General conditions:

– T_A= 25 C, unless T_Cis specified.

º

Overtemperature Protection

– Shut down pin left open circuit.

– Trim or R input not connected.

The converters are protected from possible overheating

by means of an internal temperature monitoring circuit.

It shuts down the unit above the internal temperature

limit and attempts to automatically restart every 50 to 60

ms. This feature prevents excessive internal

temperature building up, which could occur during

heavy overload conditions.

Output Overvoltage Protection

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. Double and dual-

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 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

feedback control circuit. This protection circuit is not

designed to withstand externally applied overvoltages.

Footprint

However, the open-frame models (option Z) leave the

factory unlacquered and may be cleaned and lacquered by

the customer, for instance together with the mother board.

Consult Power-One for the types of cleaning agents.

Installation Instructions

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.

Isolation

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 guarantee 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.

The converter must be connected to a secondary circuit.

Check for hazardous voltages before altering any

connections.

Furthermore, the output 1 is accurately regulated like the

single output models. The Trim input (pin 3) is not

connected.

The standard models with suffix -8 are rated up to T_A

=85 °C (see Table: Temperature Specifications).

The -8 models will provide the output power in the

derating curve specified in the fig. below with free air

convection cooling.

Option i: Inhibit

Excludes the shutdown function.

The output(s) of the converter may be enabled or disabled

by means of a logic signal (TTL, CMOS, etc.) applied to the

inhibit pin. No output voltage overshoot will occur, when the

unit is turned on. If the inhibit function is not required, the

inhibit pin should be connected to Vi– to enable the output

(active low logic, fail safe).

EC Declaration of Conformity

We

Power-One AG

Ackerstrasse 56, CH-8610 Uster

declare under our sole responsibility that 20/40IMX15 and 110IMY15 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 60950:2000 (=IEC 60950:2000)

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 20/40IMX15 and

110IMY15 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.
