Reliability The failure rate (λ) and mean time between failures (MTBF= 1/λ) is calculated at max output power and an operating ambient temperature (TA) of +40°C. Ericsson Power Modules uses Telcordia SR-332 Issue 2 Method 1 to calculate the mean steady-state failure rate and standard deviation (σ). Telcordia SR-332 Issue 2 also provides techniques to estimate the upper confidence levels of failure rates based on the mean and standard deviation. Mean steady-state failure rate, λ Std. deviation, σ 214 nFailures/h 34.5 nFailures/h MTBF (mean value) for the PKB series = 4.7 Mh. MTBF at 90% confidence level = 3.9 Mh Compatibility with RoHS requirements The products are compatible with the relevant clauses and requirements of the RoHS directive 2002/95/EC and have a maximum concentration value of 0.1% by weight in homogeneous materials for lead, mercury, hexavalent chromium, PBB and PBDE and of 0.01% by weight in homogeneous materials for cadmium. Exemptions in the RoHS directive utilized in Ericsson Power Modules products are found in the Statement of Compliance document. Ericsson Power Modules fulfills and will continuously fulfill all its obligations under regulation (EC) No 1907/2006 concerning the registration, evaluation, authorization and restriction of chemicals (REACH) as they enter into force and is through product materials declarations preparing for the obligations to communicate information on substances in the products. Quality Statement The products are designed and manufactured in an industrial environment where quality systems and methods like ISO 9000, Six Sigma, and SPC are intensively in use to boost the continuous improvements strategy.

PRODUCT SPECIFICATION 3 (4) Prepared (also subject responsible if other) No. EZHIXZH 1/1301-BMR 636 Uen Approved Checked Date Rev Reference SEC/D (Julia You) MICJOHN 2011-02-24 C Safety Specification General information Ericsson Power Modules DC/DC converters and DC/DC regulators are designed in accordance with safety standards IEC/EN/UL 60950-1 Safety of Information Technology Equipment. IEC/EN/UL 60950-1 contains requirements to prevent injury or damage due to the following hazards:

Electrical shock
Energy hazards
Fire
Mechanical and heat hazards
Radiation hazards
Chemical hazards On-board DC/DC converters and DC/DC regulators are defined as component power supplies. As components they cannot fully comply with the provisions of any safety requirements without “Conditions of Acceptability”. Clearance between conductors and between conductive parts of the component power supply and conductors on the board in the final product must meet the applicable safety requirements. Certain conditions of acceptability apply for component power supplies with limited stand-off (see Mechanical Information for further information). It is the responsibility of the installer to ensure that the final product housing these components complies with the requirements of all applicable safety standards and regulations for the final product. Component power supplies for general use should comply with the requirements in IEC 60950-1, EN 60950-1 and UL 60950-1 Safety of Information Technology Equipment. There are other more product related standards, e.g. IEEE 802.3 CSMA/CD (Ethernet) Access Method, and ETS-300132-2 Power supply interface at the input to telecommunications equipment, operated by direct current (dc), but all of these standards are based on IEC/EN/UL 60950-1 with regards to safety. Ericsson Power Modules DC/DC converters and DC/DC regulators are UL 60950-1 recognized and certified in accordance with EN 60950-1. The flammability rating for all construction parts of the products meet requirements for V-0 class material according to IEC 60695-11-10, Fire hazard testing, test flames — 50 W horizontal and vertical flame test methods. The products should be installed in the end-use equipment, in accordance with the requirements of the ultimate application. Normally the output of the DC/DC converter is considered as SELV (Safety Extra Low Voltage) and the input source must be isolated by minimum Double or Reinforced Insulation from the primary circuit (AC mains) in accordance with IEC/EN/UL 60950-1. Isolated DC/DC converters It is recommended that a slow blow fuse is to be used at the input of each DC/DC converter. If an input filter is used in the circuit the fuse should be placed in front of the input filter. In the rare event of a component problem that imposes a short circuit on the input source, this fuse will provide the following functions:
Isolate the fault from the input power source so as not to affect the operation of other parts of the system.
Protect the distribution wiring from excessive current and power loss thus preventing hazardous overheating. The galvanic isolation is verified in an electric strength test. The test voltage (V iso) between input and output is 1500 Vdc or 2250 Vdc (refer to product specification).

24 V DC systems

The input voltage to the DC/DC converter is SELV (Safety Extra Low Voltage) and the output remains SELV under normal and abnormal operating conditions. 48 and 60 V DC systems If the input voltage to the DC/DC converter is 75 Vdc or less, then the output remains SELV (Safety Extra Low Voltage) under normal and abnormal operating conditions. Single fault testing in the input power supply circuit should be performed with the DC/DC converter connected to demonstrate that the input voltage does not exceed 75 Vdc. If the input power source circuit is a DC power system, the source may be treated as a TNV-2 circuit and testing has demonstrated compliance with SELV limits in accordance with IEC/EN/UL60950-1. Non-isolated DC/DC regulators The input voltage to the DC/DC regulator is SELV (Safety Extra Low Voltage) and the output remains SELV under normal and abnormal operating conditions.

It is also important to consider the stand-off of the DC/DC converter. If a ground layer is used, it should be connected to the output of the DC/DC converter and the equipment ground or chassis. A ground layer will increase the stray capacitance in the PCB and improve the high frequency EMC performance. Output ripple and noise Output ripple and noise measured according to figure below.

PRODUCT SPECIFICATION 2 (5) Prepared (also subject responsible if other) No. EJUNGYA 3/1301-BMR 636 Uen Approved Checked Date Rev Reference SEC/D (Julia You) ESHUHAN 2008-1-11 A Operating information Input Voltage The input voltage range 36 to 75Vdc meets the requirements of the European Telecom Standard ETS 300 132-2 for normal input voltage range in 48 and 60 Vdc systems, -40.5 to - 57.0 V and 50.0 to -72 V respectively. At input voltages exceeding 75 V, the power loss will be higher than at normal input voltage and T ref must be limited to absolute max +110°C. The absolute maximum continuous input voltage is 80 Vdc. Turn-off Input Voltage The DC/DC converters monitor the input voltage and will turn on and turn off at predetermined levels. The minimum hysteresis between turn on and turn off input voltage is 3V. Remote Control (RC) The products are fitted with a remote control function referenced to the primary negative input connection (- In), with negative and positive logic options available. The RC function allows the converter to be turned on/off by an external device like a semiconductor or mechanical switch. The RC pin has an internal pull up resistor to Vcc pin of controller IC. The maximum required sink current is 1 mA. When the RC pin is left open, the voltage generated on the RC pin is around 6 V. The second option is positive logic remote control, which can be ordered by adding the suffix P to the end of the part number. The converter will turn on when the input voltage is applied with the RC pin open. Turn off is achieved by connecting the RC pin to the - In. To ensure safe turn off the voltage difference between RC pin and the - In pin shall be less than 1V. The converter will restart automatically when this connection is opened. See Design Note 021 for detailed information. Input and Output Impedance The impedance of both the input source and the load will interact with the impedance of the DC/DC converter. It is important that the input source has low characteristic impedance. The converters are designed for stable operation without external capacitors connected to the input or output. The performance in some applications can be enhanced by addition of external capacitance as described under External Decoupling Capacitors. If the input voltage source contains significant inductance, the addition of a 100 µF capacitor across the input of the converter will ensure stable operation. The capacitor is not required when powering the DC/DC converter from an input source with an inductance below 10 µH. External Decoupling Capacitors When powering loads with significant dynamic current requirements, the voltage regulation at the point of load can be improved b y addition of decoupling capacitors at the load. The most effective technique is to locate low ESR ceramic and electrolytic capacitors as close to the load as possible, using several parallel capacitors to lower the effective ESR. The ceramic capacitors will handle high-frequency dynamic load changes while the electrolytic capacitors are used to handle low frequency dynamic load changes. Ceramic capacitors will also reduce any high frequency noise at the load. It is equally important to use low resistance and low inductance PCB layouts and cabling. External decoupling capacitors will become part of the control loop of the DC/DC converter and may affect the stability margins. As a rule of thumb, 100 µF/A of output current can be added without any additional analysis. The ESR of the capacitors is a very important parameter. Power Modules guarantee stable operation with a verified ESR value of >10 mΩ across the output connections. For further information please contact your local Ericsson Power Modules representative. Output Voltage Adjust (Vadj) The DC/DC converters have an Output Voltage Adjust pin (Vadj). This pin can be used to adjust the output voltage above or below Output voltage initial setting. When increasing the output voltage, the voltage at the output pins (including any remote sense compensation ) must be kept below the threshold of the over volta ge protection, (OVP) to prevent the converter from shutting down. At increased output voltages the maximum power rating of the converter remains the same, and the max output current must be decreased correspondingly. To increase the voltage the resistor should be connected between the V adj pin and +Sense pin. The resistor value of the Output voltage adjust function is according to information given under the Output section for the respective product. To decrease the output voltage, the resistor should be connected between the Vadj pin and Sense pin.

It is not recommended to parallel the converters without using external current sharing circuits. See Design Note 006 for detailed information. Remote Sense The DC/DC converters have remote sense that can be used to compensate for voltage drops between the output and the point of load. The sense traces should be located close to the PCB ground layer to reduce noise susceptibility. The remote sense circuitry will compensate for up to 10% voltage drop between output pins and the point of load. If the remote sense is not needed +Sense should be connected to +Out and -Sense should be connected to -Out. Over Temperature Protection (OTP) The converters are protected from thermal overload by the control IC. When T ref as defined in thermal consideration section exceeds 135°C the converter will shut down. The DC/DC converter will make continuous attempts to start up (non- latching mode) and resume normal operation automatically when the temperature has dropped >10°C below the temperature threshold. Over Voltage Protection (OVP) The converters have output over voltage protection that will shut down the converter in over voltage conditions. The converter will make continuous attempts to start up (non- latching mode) and resume normal operation automatically after removal of the over voltage condition. Over Current Protection (OCP) The converters include current limiting circuitry for protection at continuous overload. The output voltage will decrease towards zero for output currents in excess of max output current (max I O). The converter will resume normal operation after removal of the overload. The load distribution should be designed for the maximum output short circuit current specified. Thermal Consideration General The converters are designed to operate in different thermal environments and sufficient cooling must be provided to ensure reliable operation. Cooling is achieved mainly by conduction, from the pins to the host board, and convection, which is dependant on the airflow across the converter. Increased airflow enhances the cooling of the converter. The Output Current Derating graph found in the Output section for each model provides the available output current vs. ambient air temperature and air velocity at V in = 53 V. The DC/DC converter is tested on a 254 x 254 mm, 35 µm (1 oz), 8-layer test board mounted vertically in a wind tunnel with a cross-section of 305 x 305 mm. Proper cooling of the DC/DC converter can be verified by measuring the temperature at positions P1, P2 and P3. The temperature at these positions should not exceed the max values provided in the table below. Note that the max value is the absolute maximum rating (non destruction) and that the electrical Output data is guaranteed up to T ref +90°C. See Design Note 019 for further information.

Temperatures above maximum Tref are not allowed and may cause degradation or permanent damage to the product. Tref is also used to define the temperature range for normal operating conditions. Tref is defined by the design and used to guarantee safety margins, proper operation and high reliability of the module. Ambient Temperature Calculation By using the thermal resistance the maximum allowed ambient temperature can be calculated. 1. The power loss is calculated by using the formula ((1/η) - 1) × output power = power losses (Pd). η = efficiency of converter. E.g 89.0 % = 0.89 2. Find the thermal resistance (Rth) in the Thermal Resistance graph found in the Output section for each model. Calculate the temperature increase (∆T). ∆T = Rth x Pd 3. Max allowed ambient temperature is: Max Tref - ∆T. E.g PKB 4711 SINB at 1m/s: 3. 120 °C 58.3°C = max ambient temperature is 61.6°C The actual temperature will be dependent on several factors such as the PCB size, number of layers and direction of airflow.

To achieve a good and reliable soldering result, make sure to follow the recommendations from the solder paste supplier, to use state-of-the-art reflow equipment and reflow profiling techniques as well as the following guidelines. A no-clean flux is recommended to avoid entrapment of cleaning fluids in cavities inside the product or between the product and the host board. The cleanin g residues may affect long time reliability and isolation voltage. Minimum Pin Temperature Recommendations Pin number 4 is chosen as reference location for the minimum pin temperature recommendations since this will likely be the coolest solder joint during the reflow process. Pin 4 for measurement of minimum solder joint temperature, TPIN Pin 2 for measurement of maximum peak product reflow temperature, TP SnPb solder processes For SnPb solder processes, a pin temperature (TPIN) in excess of the solder melting temperature, (TL, +183°C for Sn63/Pb37) for more than 30 seconds, and a peak temperature of +210°C is recommended to ensure a reliable solder joint. Lead-free (Pb-free) solder processes For Pb-free solder processes, a pin temperature (TPIN) in excess of the solder melting temperature (TL, +217 to +221°C for Sn/Ag/Cu solder alloys) for more than 30 seconds, and a peak temperature of +235°C on all solder joints is recommended to ensure a reliable solder joint. Peak Product Temperature Requirements Pin number 2 is chosen as reference location for the maximum (peak) allowed product temperature (T P) since this will likely be the warmest part of the product during the reflow process. To avoid damage or performance degradation of the product, the reflow profile should be optimized to avoid excessive heating. A sufficiently extended preheat time is recommended to ensure an even temperature across the host PCB, for both small and large devices. To reduce the risk of excessive heating is also recommended to reduce the time in the reflow zone as much as possible.
