Description
The CPD Series are highly reliable power supplies for CompactPCI(R) systems, which are increasingly used in communications, industrial, military, aerospace, and other applications. These power supplies offer high power density in plug-in modules that meet the requirements of the PICMG(R) power interface specification for CompactPCI(R) systems. The converters use the patented EDGETM technology and provide important advantages such as flexible output power, extremely high efficiency, excellent reliability, full input-to-output isolation, negligible inrush current, hot swap capability, soft start, and overtemperature protection. The inputs are protected against surges and transients occurring on the source lines and cover an input voltage range from 36 VDC up to 75 VDC. The outputs have continuous overload, open-circuit, and short-circuit protection. LEDs on the front panel, a temperature warning signal, and a fail signal indicate the status of the power supply. Voltage suppressor diodes protect the input against overvoltage. Full n+1 redundant operating mode is made by integrated ORing FETs / diodes. When several converters are connected in parallel, a single-wire connection between converters ensures current sharing. The converters are designed as two separate forward converters with synchronous rectifiers at the outputs. The switching frequency is fixed at approx. 135 kHz. The aluminium case acts as a heat sink and as RFI shield. It is particularly suitable for vertical mounting in 19" rack systems, but it can also be mounted in any other position as long as the necessary airflow is ensured. The connector is a 47-pin type from Positronic.

Functional Description
The converter input is protected against surges and transients occurring on the source lines. The highly efficient input filter and the active inrush limiter ensure a very low inrush current of short duration. This prevents circuit
breakers and fuses from being damaged at switch on. The converter is equipped with two independent high efficiency 2-switch forward converters, switching 180 out of phase to minimize ripple current at the input. Both converters are fully regulated. On the secondary side, two

high current synchronous rectifiers supply the 5 V and 3.3 V outputs with up to 40 A. The secondary controlled +12 V post regulator is supplied by an additional winding of the 3.3 V main transformer, and the linear regulator for the -12 V output is supplied by the output choke of the +12 V output. After rectification, the output filter reduces ripple and noise to a minimum without compromising the dynamic response. All outputs are protected from the bus by decoupling FETs or diodes. A current monitor calculates the output power. As soon as the output power exceeds the maximum threshold level, the converter starts to reduce the output power by decreasing the output voltages.
In contrast to the outputs 5 V, 3.3 V and +12 V with active current sharing, the -12 V output has a droop characteristic for passive current sharing. Each converter has a switching frequency of around 135 kHz. Power-One's Efficient Dual Geometric Edge (EDGETM) Technology facilitates high current density, increases reliability by reducing component stresses, and decreases the amount of heat dissipated. The backbone of this patented technology is an interleaved, multichannel forward converter utilising transitional resonant switching techniques and proprietary leading and trailingedge pulse width modulation. It has a proven track record in high-availability power solutions.

Input Fuse A fuse mounted inside the converter protects the module against further damage in the case of a failure. The fuse cannot be made externally accessible. Reverse polarity at the input will cause the fuse to blow but no other damage.
Note: Fuse is not customer-accessible.
Note: The inrush current limitation is achieved using an electronic circuitry. For effective limitation the converter should not be switched on and off more frequently than every 8 seconds.
Input Transient Protection A metal oxide VDR (Voltage Dependent Resistor) together with the input fuse and suppressor diode form an effective protection against high input voltage transients, which typically occur in most installations. The CPD Series input range and input filters have been designed and tested to meet the requirements of EN 61000-4-5, criterion B. Reverse Polarity The converters are not protected against reverse polarity at the input to avoid unwanted power loss. In case of reversed input voltage, the suppressor diode conducts blowing the fuse, but preventing further damage.
Table 3: Fuse specification

Inrush Current Limitation The CPD Series incorporates an active inrush current limiter in the input circuitry, which reduces the peak inrush current value by a factor of 10 - 15 to protect connectors and switching devices from damage.

Hold-up Time For extended hold-up time, use external output capacitors or decoupling diodes and input capacitors of adequate size. Formula for additional external input capacitor 2 * Po * (t h total - t h) * 100 C i ext = -------------------- * (Vti2 - Vi min2) where as: C i ext = = Po = th total = th = Vi min = Vti = Hot Swap Hot swap is possible. Using the hot-swap capability, the output voltages may deviate dynamically by max. 5% during the plug-in / plug-out operations. Output Protection and Current Limitation The outputs are fully protected against continuous open circuit (no load) and also against continuous short circuit.

All outputs have a constant current limitation with a rectangular characteristic (see figure below). The total current from the main power trains Vo1, Vo2 and Vo3 is limited by Po max. So there is a free choice of load distribution between these outputs.

Thermal Considerations If a converter CPD is mounted in an upright position with air flow of 250 LFM (CPD200) or 400 LFM (CPD250) allowing unrestricted forced air cooling, and is operated at its nominal input voltage and power at maximum ambient temperature TA max (see: Temperatures), the temperature measured at the measurement point of the case temperature TC (see: Mechanical Data) will approach the indicated maximum value TC max (105 C) after an initial warm-up phase. However, the relationship between TA and TC depends heavily on the operating conditions and system integration. The thermal conditions are influenced significantly by the input voltage, the output current, the airflow, and the temperature of the adjacent elements and surfaces. TA max is therefore contrary to TC max only an indicative value.
Po /Po nom 250 LFM = 1.25 m/s 1.0
05190-CPA200
Caution: The installer must ensure that under all operating conditions TC remains within the limits shown in the diagrams fig. 3 valid for a converter mounted in free and quasi-stationary air, allowing unrestricted convection cooling. Note: Forced-air cooling or an additional heat sink can improve the reliability or allow TA to be increased above TA max provided that TC max is not exceeded.
Thermal Protection A temperature sensor fitted on the main PCB provides an over temperature warning (degrade) signal 15 C before the temperature Tc max at which the thermal derating begins to reduce the output power. The output power returns to the nominal value, if the temperature drops back below this limit. See Temperature Warning and Shut-Down.

Auxiliary Functions
Inhibit The inhibit input enables (logic high, pull up) or disables (logic low, pull down) all outputs, if a logic signal (TTL, CMOS) is applied. In systems consisting of several converters this feature may be used to control the activation sequence of the converters by means of logic signals, or to enable the source to start up, before full load is applied.
Note: If this function is not used, the inhibit pin 39 can be left open (not connected). If pin 39 is connected to a return (e.g.
06153b
pin 24), the internal logic will disable all outputs. The inhibit input is protected by a decoupling diode.

Enable Connect enable pin 27 (EN#) with signal return pin 22 (RTN) externally to start the converter. Pin 27 is shorter than the others ensuring startup only when all other pins are already connected to the system providing a true hotswap capability. Temperature Warning and Shut-Down The temperature warning circuitry monitors the case temperature. Its output signal changes from high to low impedance, when the case temperature exceeds the upper threshold level, and changes back to high impedance, when the case temperature falls below the lower threshold level. Pin 38 (degrade signal VDEG#) is internally connected via the collector-emitter path of an NPN transistor to the signal return pin 22. The current I DEG# through should not exceed 40 mA. To prevent the NPN transistor from damage, VDEG# should not exceed 40 V. If the case temperature TC exceeds 105 C, the converter will be disabled. It resumes operation, once TC falls below 105 C.
11056a
Power Fail Signal The power fail circuitry monitors the input voltage and all output voltages. Its output signal Vfail changes from high to low impedance, when one of the monitored voltages falls below the threshold level; Vfail changes back to high impedance, when the monitored voltage exceeds the threshold level again. The threshold levels correspond to approx. 90% of Vi min and approx. 85% of Vo nom. Connector pin 42 (fail signal Vfail) is internally connected via the drain-source path of a JFET (self-conducting type) to the signal return pin 22. The current Ifail should not exceed 2.5 mA. The JFET is not protected against overvoltage; Vfail should not exceed 40 V.

Active Current Sharing for Vo1, Vo2, Vo3 The current sharing facility, consisting of a single-wire link, should be used, where several converters are operated in parallel connection, for example, high reliability n+1 redundant systems or systems providing higher output power. Not more than six converters should be connected in parallel. Using this feature reduces the stress on the individual converters and improves the reliablity of the system. Interconnection of the current sharing terminals causes the converters to share the output current evenly. In n+1 redundant systems a failure of a single converter will not lead to a system failure, since the outputs are already decoupled by FETs and diodes internally. Passive Current Sharing for Vo4 The output voltage changes slightly with the output current (droop characteristic) ensuring automatic current sharing
without further precautions, when several converters are connected in parallel. An increase in output current decreases the output voltage according to the formula: Vo = 12 V + (0.5 -

Installation Instructions
These converters are components, intended exclusively for installation within other equipment by an industrial assembly process or by a professionally, competent person. Installation must strictly follow the national safety regulations in respect of the enclosure, mounting, creepage distances, clearance, casualty markings, and segregation requirements of the end-use application. Connection to the system shall be made via the mating female connector (see fig. 15). Other installation methods may not meet the safety requirements. Check for hazardous voltages before altering any connections. The converters are provided with a leading pin no. 45, which is reliably connected to the case. For safety reasons it is essential to connect this pin to the protective earth of the supply system, see also: Safety of Operator-Accessible Output Circuits.
Standards and Approvals The converters correspond to class I equipment. All converters are UL-recognized according to UL 60950 and CAN/CSA C22.2 No. 60950, and approved by TUV to IEC/EN 60950-1:2001. The following considerations have been made during design concerning safety : * Build-in component * Basic insulation between input and output, based on 75 VDC. The input is identified as TNV-2. * Operational insulation between output(s) and case * Use in a pollution degree 2 environment. The converters are subject to manufacturing surveillance in accordance with the above mentioned UL standards and ISO 9001:2000. Isolation
The electric strength test is performed as factory test in The Vi input (pin no. 46) is internally fused. This fuse is accordance with EN 50116 and EN/IEC 60950 and designed to protect the converter in case of over current, should not be repeated in the field (see table Isolation). but may not be able to satisfy all customer requirements. Power-One will not honour any guarantee claims External fuses in the wiring to one or both input pins (no. 46 resulting from electric strength field tests. and/or no. 47) may therefore be necessary to ensure compliance with local requirements. Table 13: Isolation
Important: If the inhibit function is not used, pin 39 (i) should be left unconnected to enable the outputs. Enable Pin 27 (EN#) should be connected to pin 22 (RTN) to enable the outputs.

Do not open the converters, or the warranty will be invalidated. Make sure that there is sufficient airflow available for convection cooling. This should be verified by measuring the case temperature, when the converter is installed and operated in the end-use application. The maximum specified case temperature TC max should not be exceeded.

According to IEC/EN 60950, subassemblies connecting input to output are pre-tested with 3 kVDC.
Make sure that a converter failure (e.g., by an internal short-circuit) does not result in a hazardous condition. Cleaning Agents The power supplies are not hermetically sealed. In order to avoid possible damage, any penetration of cleaning fluids is to be avoided.
Protection Degree The converters correspond to protection degree IP 20, provided that the female connector is fitted. Safety of Operator-Accessible Output Circuits If the output circuit of a DC-DC converter is operatoraccessible, it shall be a SELV circuit according to the IEC/EN 60950 related safety standards. However, it is the sole responsibility of the installer to ensure the compliance with the relevant and applicable safety regulations.
