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/off ratio) of the main switch. The regulator starts operating only when the input voltage exceeds the trigger level of the UVL (undervoltage lockout). These regulators are ideal for a wide range of applications, where input to output isolation is not necessary or is already provided by an external front end (e.g., a transformer with rectifier). To optimize customers needs, additional options and accessories are available. 0306b V i I i C e + Input Filter Vi+ Bead C i Control circuit + Vo+ i I o V o R Gi Go Fig. Block diagram.

Under practical operating conditions, T A may exceed 7 C, provided that additional measures (heat sink, fan etc.) are taken to ensure that T C does not exceed T C max. Output protection and Short Circuit Behavior A voltage suppressor diode, which in worst case conditions fails into a short circuit, protects the output against an internally generated overvoltage. 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. 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 0 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.

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] 5 0600a converters, this feature can be used, for example, to control the activation sequence of the converters by a logic signal (TTL, C- MOS, etc.). No output voltage overshoot will occur at switch-on. Note: With open i-pin, the output is enabled.

Vi+ 5.4 Gi Safety and Installation Instructions Installation Instruction 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. Check for hazardous voltages before connecting. The input and the output circuit are not separated, i.e. the negative path is internally interconnected. Do not open the regulator! Ensure that a regulator failure (e.g. by an internal short-circuit) does not result in a hazardous condition. Cleaning Liquids 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 30 (IP 0, if equipped with option P). It applies only if the regulator is soldered to the mother board. Standards and Approvals All switching regulators have been approved according to the latest edition of IEC/EN 60950- and UL/CSA 60950- The regulators have been evaluated for: BCD005-G Rev AE, 3-Jul-07 The Power Partners.

Building in The use in a pollution degree environment Connecting the input to a secondary circuit, which is subject to a maximum transient rating of 500 V. The switching regulators are subject to manufacturing surveillance in accordance with the above mentioned standards and with ISO 900:008. Isolation Electric strength test voltage between input connected with output against case: 500 VDC, s (for some PSA/PSR models only with version V03 or higher). These tests are performed in the factory as routine test in accordance with EN 5054 and EN 60950. Railway Application The regulators have been developed observing the railway standards EN 5055 and EN 50. 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. R Control (Output Voltage Adjust) Note: With open R input, V o V o nom. Vi+ Gi V ref =.5 V + Fig. Voltage adjustment via R-input The output voltage V o can either be adjusted with an external voltage source (V ext ) or with an external resistor (R or R ). The adjustment range is 0 08% of V o nom.

Note: With option R, the ouput voltage V o is adjusted to 08% of V o nom, if the regulator doesn t have option Y in addition. Potentiometer 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 90 08% of V o nom. However, the minimum differential voltage V i o min between input and output specified in Electrical Input Data must be observed. Note: Option P is not recommended, if several regulators are operated in parallel connection. Y Solder Pins Models with rectangular pins.0 0.5 mm (length 6.5 mm). Such regulators can be fitted to PCB boards (through-plated holes with.3 to.5 mm). G RoHS Compliance Models with G are RoHS-compliant for all six substances.

Accessories A variety of electrical and mechanical accessories are available including: Filters and ring core chockes for ripple and interference reduction; see table 9. Tags and isolation pads for easy and safe PCB-mounting Adapters for chassis and DIN-rail mounting Isolation Pads for PCB Mounting In applications, where PCB mounting converters are placed on top of double sided boards, the use of an isolation pad is recommended. This fibre foil avoids short circuits and provide excellent protection against possible damage to tracks. Part number: HZZ003-G 50 5 0.5 8.7 6.3.
