ericsson power modules, march 2007 pmb 4518t wp datasheet 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. 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. 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. iec61204-7 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. safety specification isolated dc/dc converters. 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. non-isolated dc/dc regulators. 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 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. 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: ? 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 (v iso ) 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. general information. en/lzt 146 049 r4a ?

) 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. the pmb 4000 series regulator can accept up to 8 mf of capacitive load on the output at full load. this gives <500 f/a of i o . 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. 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 2x22 f external input capaci- f external input capaci- f external input capaci - tance with low esr should be added. a minimum of 150 f external output capacitance, low esr, f external output capacitance, low esr, f external output capacitance, low esr, should be added for the converter to operate properly at full load. en/lzt 146 049 r4a ? ericsson power modules, march 2007 pmb 4518t wp datasheet operating information 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 parallel - ing, 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. a combination of low esr and output capacitance exceeding 8 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 m ? . en/lzt 146 049 r4a ? ericsson power modules, march 2007 pmb 4518t wp datasheet thermal considerations general 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 (t ref ). calculation of ambient temperature by using the thermal resistance the maximum allowed ambient temperature can be calculated. a. the powerloss is calculated by using the formula ((1/ ) - 1) output power = power losses. = efficiency of regulator. example: 95% = 0.95 b. find the value of the thermal resistance r th tref-a in the dia - gram by using the airflow speed at the module. take the ther - mal resistance powerloss to get the temperature increase. thermal resistance vs. airspeed measured at the regulator. c. max allowed calculated ambient temperature is: max t ref of dc/dc regulator - temperature increase. example: 5v input, 1.8 v output at 1m/s, full load: b. 3.2 w 9 c/w = 28.8 c c. 90 c - 28.8 c = max ambient temperature is 61.2 c the real temperature will be dependent on several factors, like pcb size and type, direction of airflow, air turbulence etc. it is recommended to verify the temperature by testing. a.
