Example:
PSA 121.5-7iPY = A positive switching regulator with a 12 V, 1.5 A output, ambient temperature range of -25...71C, inhibit input, potentiometer and small soldering pins.
Functional Description
The switching regulators are using the buck converter topology. See also: Technical Information: Topologies. 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 in the form of flux. 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 on to off duty 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 optimise customer's needs, additional options and accessories are available.

Parallel and Series Connection Outputs of equal nominal voltages can be parallel-connected. However, the use of a single unit with higher output power, because of its power dissipation, is always a 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 10 K. Outputs can be series-connected with any other module. In series-connection the maximum output current is limited by the lowest current limitation. Electrically separated source voltages are needed for each module! Short Circuit Behaviour A constant current limitation circuit holds the output current almost constant whenever an overload or a short circuit is applied to the regulator's output. It acts self-protecting and recovers - in contrary to the fold back method - automatically after removal of the overload or short circuit condition.

Fig. 3 Dynamic load regulation. Thermal Considerations When a switching regulator is located in free, quasi-stationary air (convection cooling) at a temperature TA = 71C and is operated at its nominal output current Io nom, the case temperature TC will not exceed 95C after the warmup phase, measured at the Measuring point of case temperature TC (see: Mechanical Data). Under practical operating conditions, the ambient temperature TA may exceed 71C, provided additional measures (heat sink, fan, etc.) are taken to ensure that the case temperature TC does not exceed its maximum value of 95C. Example: Sufficient forced cooling allows TA max = 85C. A simple check of the case temperature TC (TC 95C) at full load ensures correct operation of the system.

Fig. 4 Output current derating versus temperature Output Protection 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. The user should ensure that systems with Power-One power supplies, in the event of a failure, do not result in an unsafe condition (fail-safe).

Auxiliary Functions
i Inhibit for Remote On and Off Note: With open i-input, output is enabled (Uo = on) The inhibit input allows the switching regulator output to be disabled via a control signal. In systems with several units, this feature can be used, for example, to control the activation sequence of the regulators by a logic signal (TTL, CMOS, etc.). An output voltage overshoot will not occur when switching on or off.

Safety and Installation Instructions
Installation Instruction Installation of the switching regulators 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 altering any connections. Connections can be made using fast-on or soldering technique. The input and the output circuit are not separated. i.e. the negative path is internally interconnected! The units should be connected to a secondary circuit. Do not open the module. Ensure that a unit failure (e.g. by an internal short-circuit) does not result in a hazardous condition. See also: Safety of operator accessible output circuit. Cleaning Agents In order to avoid possible damage, any penetration of cleaning fluids is to be prevented, since the power supplies are not hermetically sealed.

Protection Degree The protection degree is IP 40, IP 20 with option P. Isolation Electric strength test voltage between input interconnected with output and case: 1500 V DC, 1 s.
This test is performed as factory test in accordance with IEC/EN 60950 and UL 1950 and should not be repeated in the field. Power-One will not honour any guarantee claims resulting from electric strength field tests.
Standards and Approvals All switching regulators are UL recognized according to UL 1950 and EN 60950 and UL recognized for Canada to CAN/CSA C22.2 No. 234-M90. The units have been evaluated for: * Building in, * Functional insulation from input to output and input/output to case, * The use in an overvoltage category II environment, * The use in a pollution degree 2 environment. The switching regulators are subject to manufacturing surveillance in accordance with the above mentioned UL and CSA and with ISO 9001 standards.
Safety of Operator Accessible Output Circuit If the output circuit of a switching regulator is operator-accessible, it shall be an SELV circuit according to IEC/EN 60950 related safety standards The following table shows some possible installation configurations, compliance with which causes the output circuit of the switching regulator to be an SELV circuit according to IEC/EN 60950 up to a nominal output voltage of 30 V. However, it is the sole responsibility of the installer or user to assure the compliance with the relevant and applicable safety regulations. More information is given in: Technical Information: Safety & EMC.

The front end output voltage should match the specified input voltage range of the switching regulator. The conductor to the Gi- terminal of the switching regulator has to be connected to earth by the installer according to the relevant safety standard, e.g. IEC/EN 60950. The installer shall provide an approved fuse (slow blow type with the lowest current rating suitable for the application, max. 12.5 A) in a non-earthed input conductor directly at the input of the switching regulator. If Vo+ is earthed, insert the fuse in the Gi- line. For UL's purpose, the fuse needs to be UL-listed. If option C is fitted, a suitable fuse is already built-in in the Vi+ line. The earth connection has to be provided by the installer according to the relevant safety standard, e.g. IEC/EN 60950. Has to be insulated from earth by double or reinforced insulation according to the relevant safety standard, based on the maximum output voltage from the front end. Page 11 of 13

PSA Series Extended Data Sheet Positive Switching Regulator (Rugged)
EC Declaration of Conformity We Power-One AG Ackerstrasse 56 CH-8610 Uster
declare under our sole responsibility that all PSx Series switching regulators carrying the CE-mark are in conformity with the provisions of the Low Voltage Directive (LVD) 73/23/ EEC of the European Communities.
Conformity with the directive is presumed by conformity wih the following harmonized standards:
* EN 61204: 1995 (= IEC 61204: 1993, modified)
Low-voltage power supply devices, d.c. output - Perfomance characteristics and safety requirements
* EN 60950: 1992 + A1: 1993 + A2 (= IEC 950 second edition 1991 + A1: 1992 +
A2: 1993) Safety of information technology equipment
The installation instructions given in the corresponding data sheet describe correct installation leading to the presumption of conformity of the end product with the LVD. All PSx Series Switching Regulatiors are components, intended exclusively for inclusion within other equipment by an industrial assembly operation or by professional installers. They must not be operated as stand alone products. Hence conformity with the Electromagnetic Compatibility Directive 89/336/EEC (EMC Directive) needs not to be declared. Nevertheless, guidance is provided in most product application notes on how conformity of the end product with the indicated EMC standards under the responsibility of the installer can be achieved, from which conformity with the EMC directive can be presumed.
