Reliability The Mean Time Between Failure (MTBF) is calculated at full output power and an operating ambient temperature (TA) of +40C, which is a typical condition in Information and Communication Technology (ICT) equipment. Different methods could be used to calculate the predicted MTBF and failure rate which may give different results. Ericsson Power Modules currently uses Telcordia SR332. Predicted MTBF for the series is: 2.6 million hours according to Telcordia SR332, issue 1, Black box technique. Telcordia SR332 is a commonly used standard method intended for reliability calculations in ICT equipment. The parts count procedure used in this method was originally modelled on the methods from MIL-HDBK-217F, Reliability Predictions of Electronic Equipment. It assumes that no reliability data is available on the actual units and devices for which the predictions are to be made, i.e. all predictions are based on generic reliability parameters.

IEC/EN/UL60950 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 Directives for the final product. Component power supplies for general use should comply with the requirements in IEC60950, EN60950 and UL60950 "Safety of information technology equipment". There are other more product related standards, e.g. IEEE802.3af "Ethernet LAN/MAN Data terminal equipment power", and ETS300132-2 "Power supply interface at the input to telecommunications equipment; part 2: DC", but all of these standards are based on IEC/EN/UL60950 with regards to safety. Ericsson Power Modules DC/DC converters and DC/DC regulators are UL60950 recognized and certified in accordance with EN60950. The flammability rating for all construction parts of the products meets requirements for V-0 class material according to IEC 60695-11-10. 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/UL60950. Isolated DC/DC converters It is recommended that a slow blow fuse with a rating twice the maximum input current per selected product 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 in the input filter or in the DC/DC converter that imposes a short circuit on the input source, this fuse will provide the following functions: * * Isolate the faulty DC/DC converter 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 (Viso) between input and output is 1500 Vdc or 2250 Vdc for 60 seconds (refer to Absolute maximum ratings). Leakage current is less than 1 A at nominal input voltage. 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 TNV2 circuit and testing has demonstrated compliance with SELV limits and isolation requirements equivalent to Basic Insulation in accordance with IEC/EN/UL60950. 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.

Operating Information EMI without filter Input Voltage The input voltage range, 4.5 - 14 V, makes the products easy to use in intermediate bus applications when powered by a non-regulated bus converter or a regulated bus converter. See Ordering Information for input voltage range. Turn-off Input Voltage Range The product monitors the input voltage and will turn-on and turn-off at configured levels. The default turn-on input voltage level setting is 4.4 V, whereas the corresponding turn-off input voltage level is 4.0 V. Hence, the default hysteresis between turn-on and turn-off input voltage is 0.4 V. Remote Control Vext Test set-up Layout Recommendations The radiated EMI performance of the product will depend on the PCB layout and ground layer design. It is also important to consider the stand-off of the product. If a ground layer is used, it should be connected to the output of the product and the equipment ground or chassis. A ground layer will increase the stray capacitance in the PCB and improve the high frequency EMC performance. CTRL GND The product is equipped with a remote control function, i.e., the CTRL pin. The remote control can be referenced to either the primary negative input connection (GND) or to an external voltage (Vext), which is a 3 - 5 V positive supply voltage in accordance with the SMBus Specification version 2.0. The CTRL function allows the product to be turned on/off by an external device like a semiconductor or mechanical switch. By default the product will turn on with the CTRL pin is left open and turn off when the CTRL pin is applied to GND. The CTRL pin has an internal pull-up resistor. The maximum required sink current is 0.5 mA. When the CTRL pin is left open, the voltage generated on the CTRL pin is max 6 V.

The ripple current rating of the capacitor must be at least 4 A rms. For highperformance/transient applications or wherever the input source performance is degraded, additional low ESR ceramic type capacitors at the input is recommended. The additional input low ESR capacitance above the minimum level insures an optimized performance. Output capacitors: The recommended output capacitor has a minimum capacitance of 680 F and a low ESR. When powering loads with significant dynamic current requirements, the voltage regulation at the point of load can be improved by 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 capacitors in parallel 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 high frequency noise at the load. It is equally important to use low resistance and low inductance PCB layouts and cabling. External decoupling capacitors are a part of the control loop of the product and may affect the stability margins. The ESR of the capacitors is a very important parameter. Stable operation is guaranteed for an ESR value of >5 m and a total capacitance in the range defined in the electrical specification. For a total capacitance outside this range or with lower ESR a re-configuration will be necessary for robust dynamic operation and stability. Please contact your local Ericsson Power Modules representative for custom configurations. Control Loop Compensation The product is configured with a robust control loop compensation which allows for a wide range operation of input and output voltages and capacitive loads as defined in the electrical specification. Please contact your local Ericsson Power Modules representative for custom configurations. 13 EN/LZT 146 401 R1B January 2009 B DC/DC Regulators, Input 4.5-14V, Output 40 A/132 W Input and Output Impedance The impedance of both the input source and the load will interact with the impedance of the product. It is important that the input source has low characteristic impedance. The products are designed for a stable operation (30 degrees phase margin) 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 Capacitors. If the input voltage source contains significant inductance, the addition of a 470 F capacitor with low ESR at the input of the product will ensure stable operation. Reference (c) Ericsson AB Load Transient Response Optimization The product incorporates a Non-Linear transient Response, NLR, loop that decreases the response time and the output voltage deviation during a load transient. The NLR results in a higher equivalent loop bandwidth than is possible using a traditional linear control loop. The product is pre-configured with appropriate NLR settings for robust and stable operation for a wide range of input voltage and a capacitive load range as defined in the electrical specification. For a specific input voltage, and capacitive load, the NLR and control loop compensation configuration can be optimized for a robust and stable operation and with an improved load transient response. Please contact your local Ericsson Power Modules representative for custom configurations. Remote Sense The product has 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 +S should be connected to VOUT and -S should be connected to GND. Output Voltage Adjust Range With Analog Output Voltage Adjust the output voltage can be set by an external resistor, RSET, which is applied between the FLEX pin and the -S pin. FLEX RSET -S Analog output voltage adjust with external resistor.

Over Temperature Protection (OTP) The products are protected from thermal overload by an internal over temperature shutdown circuit. When TP1 as defined in thermal consideration section exceeds 120C the product will shut down. The product will make continuous attempts to start up (non-latching mode) and resume normal operation automatically when the temperature has dropped >15C below the temperature threshold. Please contact your local Ericsson Power Modules representative for custom configurations. Rev Reference 14 EN/LZT 146 401 R1B January 2009 B (c) Ericsson AB Over Current Protection (OCP) The product includes current limiting circuitry for protection at continuous overload. The product will shut down immediately for output currents in excess of the current limit, Ilim. The product will try to restart every 70 ms, i.e., hiccup mode, and resume normal operation after removal of the overload. The load distribution should be designed for the maximum output short circuit current specified. Please contact your local Ericsson Power Modules representative for custom configurations. Soft-start Power Up The soft-start control introduces a time-delay (default setting 10 ms) before allowing the output voltage to rise. The default rise time of the ramp up is 10 ms. Power-up is hence completed within 20 ms in default configuration using remote control. When starting by applying input voltage the control circuit bootup time adds an additional 10 ms delay. Please contact your local Ericsson Power Modules representative for custom configurations. Margin Up/Down Controls Not available in the current version. Please contact your local Ericsson Power Modules representative for custom configurations. Pre-Bias Startup Capability Pre-bias startup often occurs in complex digital systems when current from another power source is fed back through a dualsupply logic component, such as FPGA or ASIC. The BMR 451 product family incorporates synchronous rectifiers, but will not sink current during startup, or turn off, or whenever a fault shuts down the product in a pre-bias condition.

Cooling is achieved mainly by conduction, from the pins to the host board, and convection, which is dependant on the airflow across the regulator. Increased airflow enhances the cooling of the regulator. 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 specified VI. The product is tested on a 254 x 254 mm, 35 m (1 oz), 8-layer test board mounted vertically in a wind tunnel with a cross-section of 608 x 203 mm. The product incorporates a wide range of monitorable power management features that are simple to implement with a minimum of external components. Additionally, the product includes protection features that continuously safeguard the load from damage due to unexpected system faults. A fault is also shown as an alert on the SALERT pin. The following product parameters can continuously be monitored by a host: Input voltage, output voltage/current, and internal temperature. Monitoring parameters can be configured to provide alerts for specific conditions. Please contact your local Ericsson Power Modules representative for custom configurations. Connections Proper cooling of the product can be verified by measuring the temperature at position P1. The temperature at this position should not exceed the max values provided in the table below. The number of points may vary with different thermal design and topology. Note that the max value is the absolute maximum rating (non destruction) and that the electrical Output data is guaranteed up to TP1 equal to 85 degrees. See Design Note 019 for further information.
