The PSA/PSR Series of positive switching regulators are designed as power supplies for electronic systems when no input-to-output isolation is required. Their major advantages include a high level of efficiency, high reliability, low output ripple, and excellent dynamic response. Models with input voltages up to 44 V are especially designed for secondary-switched and battery-driven mobile applications. The regulators are suitable for railway applications according to EN 0 and EN 0. The case design allows for operation up to 7 C. The PSA/PSR Series are designed for wall or chassis mounting with faston connections or with solder pins for insertion into a PCB. Various options are available to adapt the regulators to different applications.

Label with input voltage range, nominal output voltage and current, protection degree, batch no., serial no., and data code including production site, version (modification status), date of production. 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 ac complished 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. 006b V i I i C e + Input Filter Vi+ Bead C i Control circuit + Vo+ i R Gi Go Option P Fig. Block diagram.

Thermal Considerations When a switching regulator is located in free, quasi-stationary air (convection cooling) at a temperature T A = 7 C and is operated at nom, the case temperature T C will be about 9 C after the warm-up phase, measured at the measuring point of case temperature T C ; see Mechanical Data. 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. / nom / nom.0 0.9 0.8 0.7 0.6 0. 0.4 0. 0. 0. 0 T A min Convection cooling Forced cooling 00a T C max 40 0 60 70 80 [ C] T A.0 0.9 0.8 0.7 0.6 0. 0.4 0. 0. 0. 0 T A min convection cooling 00a forced cooling 0 60 70 80 90 C T C max T A Fig. 4a Output current versus temperature (models -) Fig. 4b Output current versus temperature (models -7 and - 9) 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 auto matically 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 sourc e voltages are needed for each regulator. / nom.0 00a 0.8 0.6 0.4 0. 0 L 0. 0.4 0.6 0.8.0. / nom Fig. Overload and short-circuit behavior versus Page 9 of 7
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 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.

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 re quirements 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 0 (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 6090- and UL/CSA 6090- The regulators have been evaluated for: 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 00 V. The switching regulators are subject to manufacturing surveillance in accordance with the above mentioned standards and with ISO 900:0. Isolation Electric strength test voltage between input connected with output against case: 00 VDC, s (for some PSA/PSR models only with version V0 or higher). These tests are performed in the factory as routine test in accordance with EN 04 and EN 6090. Railway Application The regulators have been developed observing the railway standards EN 0 and EN 0. All boards are coated with a protective lacquer. Page 4 of 7
