3 Functional Description The switching regulators use the buck converter topology. The input is not electrically isolated from the output. During the on period of the switching transistor, current is transferred to the output, and energy is stored in the output choke. During the off period, this energy forces the current to continue flowing through the output, to the load, and back through the freewheeling diode. Regulation is accomplished by varying the duty cycle (on to off ratio) of the power switch. These regulators are ideal for a wide range of applications, where input to output isolation is not necessary, or where already provided by an external front end (e.g., a transformer with rectifier). To optimize customer s needs, additional options and accessories are available. 3a I i Vi+ Option C Input Filter Option L Vo+ i I o V i Control circuit Option C R V o G Gi Go Option P Fig. Block diagram PSB BCD226-G Rev AA, 8-May-2 Page 3 of 5

9 Under practical operating conditions, the T A may exceed 7 C, provided that additional measures (heat sink, fan, etc.) are taken to ensure that the case temperature T C does not exceed T C max. The regulators with V i max = 44 V withstand 56 V for 2 s in order to comply with railway standards. However, I o max is only continuously available for V i 8 V or for reduced T A and T C ; see fig. 4c. For operation of regulators with V i max = 44 V at T A 46 C, an internal PTC (thermistor) starts reducing I o L, if V i is greater than 8 V. At most unfavorable conditions, I o L is reduced by A; see fig. 5.

Such an overvoltage could occur due to a failure of either the control circuit or the switching transistor. The output protection is not designed to withstand externally applied overvoltages. A constant current limitation circuit holds the output current almost constant, when an overload or a short circuit is applied to the output. It acts self-protecting and recovers automatically after removal of the overload or short circuit condition. V i V o /V o nom I o max Fig. 6b Short-circuit behaviour V o versus I o for regulators with V i max = 44 V. Parallel and Series Connection Outputs of equal nominal voltages can be parallel-connected. However, the use of a single regulator with higher output power, is always the better solution. In parallel-connected operation, one or several outputs may operate continuously at their current limit knee-point which will cause an increase of the heat generation. Consequently, the max. ambient temperature should be reduced by K. Outputs can be series-connected with any other regulator. In series-connection the maximum output current is limited by the lowest current limitation, but electrically separated source voltages are needed for each regulator.

10 Auxiliary Functions i Inhibit (Remote On / Off) The inhibit input allows the switching regulator output to be disabled via a control signal. In systems with several I inh [ma] Output on V inh =.8 V V inh = 2.4 V 634a Output off V Fig. 7 Typical inhibit current I inh versus inhibit voltage V inh 69a V inh converters, this feature can be used, for example, to control the activation sequence of the converters by a logic signal (TTL, C- MOS, etc.). An output voltage overshoot will not occur, when switching on or off. Note: With open i-input, the output is enabled. R Control (Output Voltage Adjust) Note: With open R input, V o V o nom. The output voltage V o can either be adjusted with an external voltage source (V ext ) or with an external resistor (R or R 2 ). The adjustment range is 8% of V o nom.

Check for hazardous voltages before connecting. Connections of PSC models can be made using fast-on or soldering technique. PSL models should be plugged into a DIN-rack The input and the output circuit are not separated, i.e., the negative path is internally interconnected. The regulators should be connected to a secondary circuit. Do not open the regulator! Ensure that a unit failure (e.g., by an internal short-circuit) does not result in a hazardous condition. Cleaning Agents In order to avoid possible damage, any penetration of cleaning fluids must be prevented, since the power supplies are not hermetically sealed. Protection Degree The protection degree is IP 3 (IP 2, if equipped with option P). It applies only, if the regulator is plugged-in or the matching female connector is properly attached. Standards and Approvals All switching regulators are class-i equipment and have been approved according to UL 695, CSA 695, and IEC/EN nd Ed. The regulators have been evaluated for: Building in The use in a pollution degree 2 environment BCD226-G Rev AA, 8-May-2 Page 3 of 5

14 Connecting the input to a secondary circuit, which is subject to a maximum transient rating of 5 V. The switching regulators are subject to manufacturing surveillance in accordance with the above mentioned standards and with ISO 9:2. Isolation Electric strength test voltage between input connected with output against case: 5 VDC, s (for some PSB models only with version V3 or higher). These tests are performed in the factory as routine test in accordance with EN 56 and IEC/EN 695. The electric strength test should not be repeated by the customer. Railway Application The regulators have been developed observing the railway standards EN 555 and EN 52. All boards are coated with a protective lacquer. Description of Options -9 Extended Temperature Range This option defines an extended temperature range as specified in table 7. P Potentiometer Note: Option P is not recommended, if several regulators are operated in parallel connection. Option P excludes R function; the R-input (pin 6) should be left open-circuit. The output voltage V o can be adjusted in the range 9 % of V o nom. However, the minimum differential voltage V i o min between input and output specified in Electrical Input Data should be observed. L Input Filter Option L is recommended to reduce superimposed interference voltages and to prevent oscillations, if input lines exceed the length of approx. 5 m in total. The fundamental wave (approx. 2 khz) of the reduced interference voltage between Vi+ and Gi has, with an input line inductance of 5 µh, a maximum magnitude of 4 mvac. The input impedance of the switching regulator at 2 khz is about 3.5 Ω. The harmonics are small in comparison with the fundamental wave. With option L, the maximum permissible additionally superimposed ripple v i of the input voltage (rectifier mode) at a specified input frequency f i has the following values: v i max = V pp at Hz or V pp = Hz/f i V C Thyristor Crowbar Option C protects the load against power supply malfunction. It is not designed to sink external currents. A fixed-value monitoring circuit checks the output voltage V o. When the trigger voltage V o c is reached, the thyristor crowbar triggers and disables the output. It may be deactivated by removal of the input voltage. In case of a defect switching transistor, the internal fuse prevents excessive current. Note: The crowbar can be reset by removal of the input voltage only. The inhibit signal cannot deactivate the thyristor. G RoHS Compliance Models with G are RoHS-compliant for all six substances. Table 9: Crowbar trigger levels Characteristics Conditions V o = 5.
