MEE1 Series Isolated 1W Single Output DC-DC Converters TECHNICAL NOTES ISOLATION VOLTAGE REPEATED HIGH-VOLTAGE ISOLATION TESTING ‘Hi Pot Test’, ‘Flash Tested’, ‘Withstand Voltage’, ‘Proof Voltage’, ‘Dielectric Withstand It is well known that repeated high-voltage isolation testing of a barrier component can Voltage’ & ‘Isolation Test Voltage’ are all terms that relate to the same thing, a test actually degrade isolation capability, to a lesser or greater degree depending on materi- voltage, applied for a specified time, across a component designed to provide electrical als, construction and environment. The MEE1 series has toroidal isolation transformers, isolation, to verify the integrity of that isolation. with no additional insulation between primary and secondary windings of enamelled Murata Power Solutions MEE1 series of DC-DC converters are all 100% production wire. While parts can be expected to withstand several times the stated test voltage, tested at their stated isolation voltage. This is 1kVDC for 1 second. the isolation capability does depend on the wire insulation. Any material, including this A question commonly asked is, “What is the continuous voltage that can be applied enamel (typically polyurethane) is susceptible to eventual chemical degradation when across the part in normal operation?” subject to very high applied voltages thus implying that the number of tests should be The MEE1 has been recognised by Underwriters Laboratory for functional insulation, strictly limited. We therefore strongly advise against repeated high voltage isolation test- both input and output should normally be maintained within SELV limits i.e. less than ing, but if it is absolutely required, that the voltage be reduced by 20% from specified 42.4V peak, or 60VDC. The isolation test voltage represents a measure of immunity to test voltage. transient voltages and the part should never be used as an element of a safety isolation This consideration equally applies to agency recognizsed parts rated for better than system. The part could be expected to function correctly with several hundred volts off- functional isolation where the wire enamel insulation is always supplemented by a set applied continuously across the isolation barrier; but then the circuitry on both sides further insulation system of physical spacing or barriers. of the barrier must be regarded as operating at an unsafe voltage and further isolation/ insulation systems must form a barrier between these circuits and any user-accessible circuitry according to safety standard requirements. SAFETY APPROVAL The MEE1 series has been recognised by Underwriters Laboratory (UL) to UL 60950 for functional insulation in a maximum ambient temperature for 3.3V & 5V input models of 60°C and for 12V, 15V and 24V models of 85°C. File number E151252 applies. The MEE1 Series of converters are not internally fused so to meet the requirements of UL 60950 an anti-surge input line fuse should always be used with ratings as defined below. MEE1S03xxxC: 1A MEE1S05xxxC: 0.7A MEE1S12xxxC: 0.2A MEE1S15xxxC: 0.2A MEE1S24xxxC: 0.16A All fuses should be UL approved and rated to at least the maximum allowable DC input voltage. UL file number E151252 applies. RoHS COMPLIANCE INFORMATION This series is compatible with RoHS soldering systems with a peak wave solder temperature of 260°C for 10 seconds. The pin termination finish on the SIP package type is Tin Plate, Hot Dipped over Matte Tin with Nickel Preplate. The DIP types are Matte Tin over Nickel Preplate. Both types in this series are backward compatible with Sn/Pb soldering systems. For further information, please visit www.murata-ps.com/rohs www.murata-ps.com/support KDC_MEE1.D01 Page 3 of 14

MEE1 Series Isolated 1W Single Output DC-DC Converters APPLICATION NOTES Minimum Load The minimum load to meet datasheet specification is 10% of the full rated load across the specified input voltage range. Lower than 10% minimum loading will result in an increase in output voltage, which may rise to typically 1.5 times the specified output voltage if the output load falls to less than 5%. Capacitive loading and start up Typical start up times for this series, with a typical input voltage rise time of 2.2μs and output capacitance of 10μF, are shown in the table below. The product series will start into a capacitance of 47μF with an increased start time, however, the maximum recommended output capacitance is 10μF.

MEE1 Series Isolated 1W Single Output DC-DC Converters APPLICATION NOTES (Continued) Output Ripple Reduction By using the values of inductance and capacitance stated, the output ripple at the rated load is lowered to 5mV p-p max. Component selection Capacitor: It is required that the ESR (Equivalent Series Resistance) should be as low as possible, ceramic types are recommended. The voltage rating should be at least twice (except for 15V output), the rated output voltage of the DC-DC converter. Inductor: The rated current of the inductor should not be less than that of the output of the DC-DC converter. At the rated current, the DC resistance of the inductor should be such that the voltage drop across the inductor is <2% of the rated voltage of the DC-DC converter. The SRF (Self Resonant Frequency) should be >20MHz.
