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. Covering a total input voltage range from 9 V up to 150 V with 4 different models. The units are available with up to quadruple outputs (electrically isolated) from 5 V to 60 V, 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 response to load and line changes. The converters are designed and built according to the international safety standards IEC/EN/UL 60950, and Table of Contents approved by TUV, UL, and cUL. The IMX35 models provide basic insulation. The circuit is comprised of 2 planar magnetics devices, and all components are automatically assembled and securly 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 present. The thermal design without using any potting material allows operation at full load up to an ambient temperature of 71 C in free air and operation up to 110 C with airflow. For extremely high vibration environments the case has holes for screw mounting.

BCD20009-G Rev AA Page 2 of 16 www.power-one.com IMX35 Series Data Sheet 35-Watt Quad-Output DC-DC Converters (R) Functional Description The IMX35 converters are comprised of 2 feedback-controlled interleaved-switching flyback power trains using current mode PWM (pulse width modulation). Each converter consists of 4 electrically isolated outputs deriving from 2 power trains. Vo1, Vo4 derive from the first power train and Vo2, Vo3 from the second one. Thus each pair of outputs is independent from the other one. Voltage regulation for each pair of outputs is achieved with passive transformer feedback from the main transformer of the power train. Each pair of outputs has the same output voltage (i.e. D05, D12, etc.). If both power trains have the same output voltage (e.g., D12D12), all outputs may be simultaneously adjusted by the Trim input (pin 5). In case of different output voltages (e.g., D05D15), the Trim1 input influences only Vo1 and Vo4. Current limitation is provided by the primary circuit for each power train and limits the possible output power for each pair of outputs. In the case of an overload on either of the power trains, which causes the output voltage to fall less than typically 60% of Vo nom, the entire converter will shut down and automatically restart in short intervals (hiccup mode). The incorporated overtemperature protection shuts down the converter in excessive overload conditions with automatic restart. 03098a Vi+ 4 16 Vo1+ PUL 1 15 Vo1- Trim/Trim1 5 W 6 17 Vo4+ PWM Ref 7 18 Vo4- SD 8 Vi- 2 n.c. 3 13 Vo2+ 14 Vo2- 12 Vo3+ 11 Vo3- 19 n.c.

A series resistor may be installed in the input line in order to further reduce this current. A built-in suppressor diode provides effective protection against input transients, which may be generated for example by short-circuits across the input lines, where the network inductance may cause high energy pulses.

BCD20009-G Rev AA Page 6 of 16 www.power-one.com IMX35 Series Data Sheet 35-Watt Quad-Output DC-DC Converters (R) Thermal Considerations Short Circuit Behavior If a converter, mounted on a PCB, is located in free, quasistationary 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 TC measured at the measuring point of case temperature (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 the surfaces and 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. The current limit characteristic shuts down the converter whenever a short circuit is applied to an output. It acts selfprotecting and automatically recovers after removal of the overload condition (hiccup mode). 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. The converters provide the specified output power with free air convection cooling. In the upper temperature range the output power derating below should be observed.

Connection in Series The outputs of one or several double output power trains may be connected in series without any precautions. Po /Po max Connection in Parallel 11047-X35 Several outputs of the same converter with equal output voltage (e.g., 5 V / 5 V) can be connected in parallel and will share their output currents almost equally. 1.0 0.8 If outputs from the same converter are being paralleled together, it is recommended that outputs from the same power trains are connected together first. 0.5 m/s = 200 LFM 0.6 natural cooling 0.4 Note: A separate application note is available for uses when all outputs are paralleled together. 0.2 0 20 40 60 80 100 C TA Fig. 5 Parallel operation of several 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 is required in true redundant systems. It is recommended not to parallel more than three units at full load. Maximum allowed output power versus ambient temperature. Overtemperature Protection The converter is protected against 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. This feature prevents excessive internal temperature building up which could occur under heavy overload conditions.

The following table indicates suitable resistor values for typical output voltages under nominal conditions (Vi nom, Io = 0.5 Io nom). 0 1.5 2.5 4.25 6.2 8 It is possible to synchronize the switching frequency of one or more converters to an external symmetrical clock signal. If this option is required, consult factory for full application details. This logic input W can be used to synchronize the oscillator to an external frequency source. This signal is edge-triggered with TTL thresholds, and requires a source frequency of 490 to 540 kHz (duty cycle 10 to 90%). The external source frequency is internally divided by 2 to define the switching frequency for the converter. If unused, this pin can be connected to V1- (pin 2) or left open-circuit. The converter provides a stable 5 V (0.1 V) reference signal on pin 7 (Ref). The output is protected by a 1 k resistor. The signal may be used also in conjunction with the Trim input (pin 5) as a limited external voltage reference. It is recommended to connect a filter capacitor (0 .1 F) between Ref and Vi-, if Ref is used. Shutdown Note: Connection of Rext to Vi+ may damage the converter. The outputs of the converters may be enabled or disabled by means of a logic signal (TTL, CMOS, etc.) applied to shut down (pin 8).

The table below indicates typical values Vo versus Vext. Applying a control voltage of 15 to 20 V will set the converter into the hiccup mode. Direct paralleling of the Trim pins of converters of the same type connected in parallel is feasible.

No output voltage overshoot will occur, when the converter is turned on.

Ensure that a converter failure (e.g., by an internal shortcircuit) does not result in a hazardous condition. Input Fuse To prevent excessive current flowing through the input supply line in case of a short-circuit in the converter, an external fuse should be installed in the non-earthed input line. We recommend a fast acting fuse specified in table 3. Standards and Approvals All converters are approved according to the standards UL 60950-1, CSA 60950-1, and IEC/EN 60950-1:2001. The converters have been evaluated for: * Building-in * Basic insulation input to output, based on their maximum input voltage * Pollution degree 2 (not option Z) * Connecting the input to a secondary circuit, which is subject to a maximum transient rating of 1500 V. 09122a 1 2 3 4 5 6 7 8 Bottom view The converters are subject to manufacturing surveillance in accordance with the above mentioned standards. 11 12 13 14 15 16 17 18 19 CB scheme is available (DE3-52559M3). Railway Applications To comply with Railway standards, all components are coated with a protective lacquer (except for option Z). Protection Degree The protection degree is IP 30 (not for option Z). Fig. 18 Footprint. The holes in the PCB should have a diameter of 1.5 mm. Cleaning Agents In order to avoid possible damage, any penetration of cleaning fluids should be prevented, since the power supplies are not hermetically sealed. 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 motherboard. Contact Power-One for the type of cleaning agents.

BCD20009-G Rev AA Page 15 of 16 www.power-one.com (R) IMX35 Series Data Sheet 35-Watt Quad-Output DC-DC Converters EC Declaration of Conformity We Power-One AG Ackerstrasse 56, CH-8610 Uster declare under our sole responsibility that IMX35 Series DC-DC converters carrying the CEmark 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 60950-1:2001 (=IEC 60950-1:2001) 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 IMX35 Series 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.
