Isolated DC/DC converters. Ericsson Power Modules DC/DC converters and DC/DC regulators are designed in accordance with safety standards IEC/EN/UL 60 950, Safety of Information Technology Equipment. It is recommended that a fast 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: 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 are defined as component power supplies. As components they cannot fully comply with the provisions of any Safety requirements without "Conditions of Acceptability". 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. * 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 product specification). Leakage current is less than 1A at nominal input voltage. 24 V dc systems. 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. IEC612047 "Safety standard for power supplies", 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 UL 60 950 recognized and certified in accordance with EN 60 950. The flammability rating for all construction parts of the products meets UL 94V-0. 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 60 950. 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 Ericsson Power Modules DC/DC converter is 75 V dc 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 V dc. 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/UL 60 950. 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 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 regulator.

PMB 4418T WP Datasheet 23 EN/LZT 146 048 R4A (c) Ericsson Power Modules, March 2007 EMC Specification Operating Information Layout Recommendation Remote Control (RC) The radiated EMI performance of the DC/DC regulator will be optimised by including a ground plane in the PCB area under the DC/DC regulator. This approach will return switching noise to ground as directly as possible, with improvements to both emission and susceptibility. The RC pin may be used to turn on or turn off the regulator using a suitable open collector function. Turn off is achieved by connecting the RC pin to the input voltage. The regulator will run in normal operation when the RC pin is left open. -FWFM < E#"> RC Regulator condition min High level OFF 1.7 Open ON referenced to GND typ max Unit 5.5 V Vi L L L . . . . . . . 'S FRVFOD Z < )[ > Vi RC Module GND Remote Sense All PMB 4000 Series DC/DC regulators have a positive remote sense pin that can be used to compensate for moderate amounts of resistance in the distribution system and allow for voltage regulation at the load or other selected point. The remote sense line will carry very little current and does not need a large cross sectional area. However, the sense line on the PCB should be located close to a ground trace or ground plane. The remote sense circuitry will compensate for up to 10% voltage drop between the sense voltage and the voltage at the output pins from VOnom. If the remote sense is not needed the sense pin should be left open. PMB 4418T WP Datasheet 24 EN/LZT 146 048 R4A (c) Ericsson Power Modules, March 2007 Operating Information Output Voltage Adjust (Vadj) Input And Output Impedance The output voltage can be set by means of an external resistor, connected to the Vadj pin. Nominal output voltage 0.75 V is set by leaving the Vadj pin open. Adjustment can only be made to increase the output voltage setting. The impedance of both the power source and the load will interact with the impedance of the DC/DC regulator. It is most important to have a low characteristic impedance, both at the input and output, as the regulators have a low energy storage capability. Use capacitors across the input if the source inductance is greater than 4.7 H. Suitable input capacitors are 22 F - 220 F low ESR ceramics. To increase: Connect a resistor between (Vadj) and (Gnd). The output voltage increases with decreasing resistor value as shown in the table below. Note that the maximum output voltage 3.63 V may not be exceeded. Minimum Required External Capacitors External input capacitors are required to increase the lifetime of the internal capacitors and to further reduce the input ripple. A minimum of 44 F external input capacitance with low ESR should be added. Rext up (kohm) = (21.007 / (VO - 0.75225)) - 5.1 Output Voltage (V) Resistor (ohm) 0.75 Open 1.0 79.691 k 1.2 41.817 k 1.5 22.990 k 1.8 14.949 k 2.5 6.919 k 3.3 3.145 k A minimum of 150 F external output capacitance , low ESR, should be added for the converter to operate properly at full load. Maximum Capacitive Load When powering loads with significant dynamic current requirements, the voltage regulation at the load can be improved by addition of decoupling capacitance at the load. The most effective technique is to locate low ESR ceramic capacitors as close to the load as possible, using several capacitors to lower the total ESR. These ceramic capacitors will handle short duration high-frequency components of dynamic load changes. In addition, higher values of capacitors (electrolytic capacitors) should be used to handle the mid-frequency components. It is equally important to use good design practice when configuring the DC distribution system. +Out Sense Low resistance and low inductance PCB layouts and cabling should be used. Remember that when using remote sensing, all resistance (including the ESR), inductance and capacitance of the distribution system is within the feedback loop of the regulator. This can affect on the regulators compensation and the resulting stability and dynamic response performance. Load Vadj Radj GND Increase Very low ESR and high capacitance must be used with care. A "rule of thumb" is that the total capacitance must never exceed typically 500-700 F if only low ESR (< 2 mW) ceramic capacitors are used. If more capacitance is needed, a combination of low ESR type and electrolytic capacitors should be used, otherwise the stability will be affected. Circuit configuration for output voltage adjust Current Limit Protection The PMB 4000 Series DC/DC regulators include current limiting circuitry that allows them to withstand continuous overloads or short circuit conditions on the output. The current limit is of hick-up mode type. The regulator will resume normal operation after removal of the overload. The load distribution system should be designed to carry the maximum output short circuit current specified. PMB 4418T WP Datasheet The PMB 4000 series regulator can accept up to 5 mF of capacitive load on the output at full load. This gives <500 F/A of IO. When using that large capacitance it is important to consider the selection of output capacitors; the resulting behavior is a combination of the amount of capacitance and ESR. 25 EN/LZT 146 048 R4A (c) Ericsson Power Modules, March 2007 Operating Information A combination of low ESR and output capacitance exceeding 5 mF can cause the regulator into over current protection mode (hick-up) due to high start up current. The output filter must therefore be designed without exceeding the above stated capacitance levels if the ESR is lower than 30-40 mW. Parallel Operation The PMB 4000 Series DC/DC regulators can be connected in parallel with a common input. Paralleling is accomplished by connecting the output voltage pins directly and using a load sharing device on the input. Layout considerations should be made to avoid load imbalance. For more details on paralleling, please consult your local applications support. Input Undervoltage Lockout The PMB 4000 Series DC/DC regulators are equipped with a lockout function for low input voltage.When the input voltage is below the undervoltage lockout limit of the regulator it will shut off. When the input voltage increases above the lockout level the regulator will turn on. PMB 4418T WP Datasheet 26 EN/LZT 146 048 R4A (c) Ericsson Power Modules, March 2007 Thermal Considerations General Calculation of ambient temperature The PMB 4000 Series DC/DC regulators are designed to operate in a variety of thermal environments, however sufficient cooling should be provided to help ensure reliable operation. Heat is removed by conduction, convection and radiation to the surrounding environment. Increased airflow enhances the heat transfer via convection. Proper cooling can be verified by measuring the temperature at the reference point (Tref). By using the thermal resistance the maximum allowed ambient temperature can be calculated. 5SFG A. The powerloss is calculated by using the formula ((1/) - 1) x output power = power losses. = efficiency of regulator. Example: 95% = 0.95 B.
