BCD20009-G Rev AC, 06-May-2013 Page 3 of 15 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 Fig. 1 Block diagram of quad-output models 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 V o 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.

An external fuse is required to limit this current.

BCD20009-G Rev AC, 06-May-2013 Page 7 of 15 Fig. 5 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. Short Circuit Behavior The current limit characteristic shuts down the converter whenever a short circuit is applied to an output. It acts self- protecting and automatically recovers after removal of the overload condition (hiccup mode). Thermal Considerations 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 specifi- cations) and is operated at its nominal input voltage and output power, the case temperature TC (TC Z with option Z) 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. T A max is therefore only an indicative value, and under practical operating conditions, the ambient temperature T A may be higher or lower than this value. Caution: The case temperature TC (or T C Z) measured at the measuring point of case temperature (see Mechanical Data) may under no circumstances exceed the specified maximum value. The installer must ensure that under all operating conditions T C (or TC Z) 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. Series and Parallel Connection The outputs of one or several double-output power trains may be connected in series respecting the current limitation. Both outputs of the same power train can always be connected in parallel in will behave like a single output. 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. If outputs of the same converter are being parallel and series- connected, it is recommended that outputs from the same power trains are parallel-connected first. This applies for instance, if 24 V shall be generated by a converter with four 12 V outputs; see fig. 7. Fig. 6 Overload switch off (hiccup mode), typical values. Note: Parallel operation of several converters may cause start- up problems. This becomes noticable in applications, where one converter is not able to deliver allone the full resistive and capacitive load current, as it is required in true redundant systems. 100 Vo [%] t 05041b 0.3 s overload short-circuit condition switch-off 1.0 0.8 0.6 0.4 0.2 20 40 60 80 100 °C Po/Po max 11047-X35a TA 0.5 m/s = 100 LFM natural cooling PWM Vi+ SD PUL 5Trim 7Ref 2Vi– Vo4– Vo1+ Vo1– Vo4+ Vo2+ Vo2– Vo3+ Vo3– JM138 3n.c. 19 n.c. –24V +24V IMX35D12D12-9 Fig. 7 Generating 24 V with an IMX35D12D12-9

Fig. 12 shows the schematic diagram for the adjustment of quad-output models. All models with equal output voltages have a Trim input at pin 5 referenced to the primary side, influencing all outputs simul- taneously.

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 of the converter. If unused, this pin can be connected to V1– (pin 2) or left open-circuit. Reference Output (Ref) The converter provides a stable 5 V (±0.1 V) reference signal on pin 7 (Ref). The output is protected by a 1 k Ω 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 µF) between Ref and Vi–, if Ref is used. Shutdown 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). If the shutdown function is not required, pin 8 should be left open-circuit: Converter operating: 2.0 to 20 V Converter disabled: –10 to 0.7 V Adjustment of the output voltage by means of an external resistor R ext is possible within the range of 100 to 105% of Vo nom. Rext should be connected between Trim (pin 5) and Vi– (pin 2). The following table indicates suitable resistor values for typical output voltages under nominal conditions ( V i nom, Io = 0.5 Io nom). Note: Connection of Rext to Vi+ may damage the converter. Adjustment by means of an external voltage source Vext For external output voltage adjustment in the range 85 to 105% of Vo nom a voltage source Vext (0 to 20 V) is required, connected to Trim or Trim1 (pin 5) and Vi–. The table below indicates typical values V o 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. Trim Vo1+ Vo2– Vext Vi+ Vi– Rext Vo1– Vo2+ 06137c Control circuit Vref = 2.5 V

BCD20009-G Rev AC, 06-May-2013 Page 10 of 15 Progr. Input Undervoltage Lockout PUL A special feature of the converters (with Rev. BA or later) is the adjustable undervoltage lockout protection, which protects the converter (and the system) from high current caused by operation at low input voltages. This ensures easier start-up in distributed power systems. The table below shows the band of switch on/off and the hysteresis. The undervoltage lockout levels may be programmed by using an external resistor R PUL between PUL and Vi– to increase the preset levels as specified in table 10.

19 n.c. Safety and Installation Instructions Pin allocation Fig. 18 Footprint. The holes in the PCB should have a diameter of 1.5 mm. Installation Instructions Installation of the 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. Connection to the system shall be made via a printed circuit board with hole diameters of 1.5 mm for the pins. The converters should be connected to a secondary circuit. Do not open the converter. Ensure that a converter failure (e.g., by an internal short- circuit) 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 safety-approved to IEC/EN 60950-1 and UL/CSA 60950-1 2 nd Ed. 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. The converters are subject to manufacturing surveillance in accordance with the above mentioned standards. CB scheme is available. 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). Cleaning Liquids In order to avoid possible damage, any penetration of cleaning fluids should be prevented, since the converters are not hermetically 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 liquids are not permitted – except washing at room temperature with isopropyl alcohol and de-inonized/destilled water (1 : 1) . Note: Cleaning liquids may damage the adhesive joints of the ferrite cores. 09122a Bottom view

If the inhibit function is not required the inhibit (pin 8) should be connected to Vi– to enable the output (active low logic, fail safe). Voltage at pin 8: Converter operating: –10 V to 0.8 V Converter disabled: 2.4 V to 20 V or left open-circuit Z: Open Frame For applications, where the protection by a housing is not necessary or in the case that the motherboard should be lacquered after fitting the converter. Note: The converters shall not be exposed to cleaning processes, as this will damage the glue of the ferrite cores. G: RoHS-6 Converters with a type designation ending by G are RoHS- compliant for all six substances.
