MEV1 Series www.murata-ps.com 3kVDC Isolated 1W Single & Dual Output DC/DC Converters Wide temperature performance at full 1 Watt load, –40°C to 85°C UL 94V-0 package material No heatsink required Industry standard pinout 3kVDC isolation (1 minute) ‘Hi Pot Test’ 5V, 12V, 15V, 24V, & 48V inputs 5V, 9V, 12V, & 15V output Fully encapsulated with toroidal magnetics No external components required No electrolytic or tantalum capacitors PRODUCT OVERVIEW The MEV series is the new high performance version of our 1W NMV series. The MEV series is more efficient and offers improved regulation performance from 1.8% for applications where a wide output voltage variation can not be tolerated. They are ideally suited for providing local supplies on control system boards with the added benefit of 3kVDC galvanic isolation to reduce switching noise. The MEV series is currently available in an industry SIP 7 or DIP 14 package. 5.4 4.2 4.6 4.5 4.5 3 3 2.5 4 2.5 2.3 2.5 3.3 2.2 2 1.8 3.3 2.4 2 1.9 5.4 4.2 5.0 4.4 4.6 3 3.1 2.5 4 2.6 2.3 2.5 3.4 2.3 2 1.8 % 81 83.5 84 85 80 83 85.5 83.5 80 82.5 83.5 85 79 81 82 82 75.5 78.5 78 79 81 83 84 84 80 82 84 83 79 81 83 84 79 82 83 83 84 86.5 87 87.5 84 86 88 88 83.5 86.5 87.5 89 84 86.5 87.5 87.5 79.5 82 82 82.5 84 86.5 87 87.5 84 86 88 88 83.5 86.5 87.5 89 84 86.5 87.5 87.5 pF 38 42 40 39 28 50 70 59 32 52 63 87 38 56 72 83 34 54 63 74 39 40 39 38 34 50 52 60 32 52 63 87 38 55 73 84 kHrs 7684 7698 7175 6496 7569 7317 6647 6279 7167 6906 6523 5916 7391 6490 6772 5957 7354 7120 7088 7238 6884 6732 6153 5419 6644 6434 5653 5267 6332 6114 5767 5002 6488 5693 5736 4915 Package Style Efficiency (Typ) mVp-p 20 30 12 20 10 20 8 15 12 15 8 15 7 15 7 15 10 20 8 20 6 15 6 15 12 20 8 20 7 15 7 15 19 35 13 25 10 20 9 20 15 30 9 20 8 15 8 15 11 20 8 15 7 15 6 15 11 25 7 20 6 15 6 15 16 30 9 20 7 15 6 15 Efficiency (Min) 6.2 5.5 5.5 5 5 3.3 3.6 2.9 5 3.5 3.5 3.5 5 3.5 3.5 3 5 3.5 3 3 6.5 5.5 5.7 5.5 5.5 3.5 3.7 3.3 5.2 3.3 3 3.2 4.5 3.3 3 3 % 233 227 226 225 98 96 94 94 79 77 76 76 50 48 48 48 26 25 26 26 234 228 228 226 98 96 93 94 79 77 76 75 50 48 48 48 Ripple & Noise (Max)2 Load Regulation (Typ) Input Current at Rated Load mA MTTF3 Power density to 0.85W/cm3 200 111 84 67 200 111 84 67 200 111 84 67 200 111 84 67 200 111 84 67 200 111 84 67 200 111 84 67 200 111 84 67 200 111 84 67 Isolation Capacitance Efficiency to 89% (Typ.)

TECHNICAL NOTES ISOLATION VOLTAGE ‘Hi Pot Test’, ‘Flash Tested’, ‘Withstand Voltage’, ‘Proof Voltage’, ‘Dielectric Withstand Voltage’ & ‘Isolation Test Voltage’ are all terms that relate to the same thing, a test voltage, applied for a specified time, across a component designed to provide electrical isolation, to verify the integrity of that isolation. Murata Power Solutions MEV1 series of DC/DC converters are all 100% production tested at their stated isolation voltage. This is 3kVDC for 1 minute. A question commonly asked is, “What is the continuous voltage that can be applied across the part in normal operation?” The MEV1 has been recognized by Underwriters Laboratory for functional insulation, both input and output should normally be maintained within SELV limits i.e. less than 42.4V peak, or 60VDC. The isolation test voltage represents a measure of immunity to transient voltages and the part should never be used as an element of a safety isolation system. The part could be expected to function correctly with several hundred volts offset applied continuously across the isolation barrier; but then the circuitry on both sides 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. REPEATED HIGH-VOLTAGE ISOLATION TESTING It is well known that repeated high-voltage isolation testing of a barrier component can actually degrade isolation capability, to a lesser or greater degree depending on materials, construction and environment. The MEV1 series has toroidal isolation transformers, with no additional insulation between primary and secondary windings of enameled wire. While parts can be expected to withstand several times the stated test voltage, the isolation capability does depend on the wire insulation. Any material, including this enamel (typically polyurethane) is susceptible to eventual chemical degradation when subject to very high applied voltages thus implying that the number of tests should be strictly limited. We therefore strongly advise against repeated high voltage isolation testing, but if it is absolutely required, that the voltage be reduced by 20% from specified test voltage. This consideration equally applies to agency recognized parts rated for better than functional isolation where the wire enamel insulation is always supplemented by a further insulation system of physical spacing or barriers. SAFETY APPROVAL The MEV1 series has been recognized by Underwriters Laboratory (UL) to UL 60950 for functional insulation in a maximum still air ambient temperature of 85°C and/or case temperature limit (case temperature measured on the face opposite the pins) as follows: MEV1SxxxxSC: 130ºC MEV1SxxxxDC: 130ºC MEV1DxxxxSC: 94ºC MEV1DxxxxDC: 96ºC The MEV1 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. MEV1x05xxxC: 1A MEV1x12xxxC: 0.375A MEV1x15xxxC: 0.375A MEV1x24xxxC: 0.2A MEV1x48xxxC: 0.1A All fuses should be UL recognized and rated to at least the maximum allowable DC input voltage. File number E151252 applies. RoHS COMPLIANT INFORMATION This series is compatible with RoHS soldering systems with a peak wave solder temperature of 300°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.

Lower than 10% minimum loading will result in an increase in output voltage, which may rise to typically double 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.

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.
