The converters are particularly suitable for use in mobile or stationary applications in transport, railways, industry, or telecommunications, where variable input voltages or high transient voltages are prevalent. 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 doubleoutput 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 insulation. Connected to a secondary circuit, these models provide SELV outputs, even if the bus voltage at the converter Table of Contents 110IMY15 models 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. 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 consideration 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.

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.

The -05- and -0503output 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. Vi+ 1 SD 4 Current limitation is provided by the primary circuit, thus limiting the total output power of double-output models. The shut-down input allows remote converter on/off. 15 Go PWM n.c. 3 11 Vo2+ Vi - 2 12 Go 2 x 2200 pF Several single-output models with 3.3 or 5.1 V output exhibit a synchronos rectifier to improve the efficiency. 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. 13 Vo1+ 17 R Fig. 2 Block diagram of -0503-models 03090 Vi+ 1 11 Vo1+ SD 4 12 Vo1- PWM Trim 3 13 Vo2+ Vi - 2 15 Vo2- Overtemperature protection will disable the converter under excessive overload conditions with automatic restart. 03039 Vi+ 1 13 Vo+ 17 n.c. 2 x 2200 pF Fig. 3 Block diagram of double-output models PWM SD 4 15 Vo- 2 x 2200 pF 1500 V V i- 2 17 R Fig. 1 Block diagram of single-output models BCD20008-G Rev AC, 26-Nov-2012 Page 4 of 19 www.power-one.com IMX15, IMS15, IMY15 Series Data Sheet 15 -Watt DC-DC Converters (R) Electrical Input Data General conditions: - TA = 25 C, unless TC is specified. - Shut-down pin left open-circuit. - Trim or R input left open-circuit.

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 selfprotecting, and automatically recovers after removal of the overload condition (hiccup mode). Parallel and Series Connection The outputs of one or several single- or double-output Vo [%] overload short-circuit condition 100 switch-off 05041b 70 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. 0 t 0.3 s Fig. 8 Overload switch-off (hiccup mode); typical values Po /Po max JM017 models can be connected in series without any precautions, taking into consideration that the highest output voltage should remain below 42 V to ensure that the output remains SELV. 1.0 0.8 0.5 m/s = 100 LFM 0.6 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. natural cooling 0.4 0.2 0 20 40 60 80 100 C TA Fig. 7 Maximum output power versus ambient temperature Note: If the 2nd output of double-output models (except 0503) is not used, connect it in parallel to the 1st output. Overtemperature Protection 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. Output Overvoltage Protection The output of single-output models as well as -0503- and -0505-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.

As a standard feature, the single- and double-output models offer adjustable output voltage(s) by using the control input R or Trim. If the control input is left open-circuit, the output voltage is set to Vo nom. For output voltages Vo > Vo nom, the minimum input voltage Vi min (see Electrical Input Data) increases proportionally to Vo/Vo nom. Single-output models with synchronous rectifier (G): The R input is referenced to the secondary side of the converter. Adjustment of the output voltage is possible by means of an external resistor connected between the R pin and either Vo+ or Vo-.

The table below indicates values Vo versus Vext (nominal conditions Vi nom, Io = 0.5 Io nom), with either parallel-connected outputs or equal load conditions on both outputs. Applying a control voltage >20 V will set the converter into a hiccup mode. Direct paralleling of the Trim pins of parallel connected converters is possible.

Connection of Rext to Vi+ may damage the converter.

Railway Applications To comply with railway standards, all components are coated with a protective lacquer (except option Z). Protection Degree and Cleaning Liquids 10005 The protection degree of the converters is IP 40, except openframe models (option Z). 11 In order to avoid possible damage, any penetration of cleaning fluids should be prevented, since the power supplies are not hermetical sealed. 12 1 13 Bottom view 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. 2 3 15 4 17 Fig. 22 Footprint Note: Cleaning liquids may damage the adhesive joints of the ferrite cores. Installation Instructions 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. 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. 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 warranty claims resulting from electric strength field tests. Table 16: Electric strength test voltages Characteristic Do not open the converter. Input to output Output to IMS15 IMX15 IMY15 output Ensure that a converter failure (e.g., by an internal shortcircuit) does not result in a hazardous condition. Factory test 1 s Equivalent DC voltage (1.7) Input Fuse Insulation resistance at 500 VDC >100 To prevent excessive current flowing through the input supply lines in case of a malfunction an external fuse should be installed in a non-earthed input supply line; see table 4 .
