NMH Series Isolated 2W Dual Output DC-DC Converters 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 NMH series of DC-DC converters are all 100% production tested at their stated isolation voltage. This is 1kVDC for 1 second. A question commonly asked is, “What is the continuous voltage that can be applied across the part in normal operation?” For a part holding no specific agency approvals, such as the NMH series, 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 NMH series has toroidal isolation transformers, with no additional insulation between primary and secondary windings of enamelled 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 recognised 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. 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.

NMH Series Isolated 2W Dual 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 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.

NMH Series Isolated 2W Dual 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. +VOUT L DC C Load Power OV Source DC C Load -VOUT L Inductor Order Codes Order Code L (μH) C (μF) SMD Through Hole NMH0505XC 47 82473C 11R473C 4.7 NMH0509XC 47 82473C 11R473C 2.2 NMH0512XC 150 82154C 11R154C 3.3 Product specification for MPS inductors can be found at: NMH0515XC 100 82104C 11R104C 3.3 1100R Series (Through Hole) NMH1205XC 47 82473C 11R473C 4.7 http://www.murata-ps.com/data/magnetics/kmp_1100r.pdf NMH1209XC 47 82473C 11R473C 2.2 NMH1212XC 150 82154C 11R154C 3.3 8200 Series (SMD) NMH1215XC 100 82104C 11R104C 3.3 http://www.murata-ps.com/data/magnetics/kmp_8200c.pdf NMH2405XC 47 82473C 11R473C 4.7 NMH2409XC 47 82473C 11R473C 2.2 NMH2412XC 150 82154C 11R154C 3.3 NMH2415XC 100 82104C 11R104C 3.3 NMH4805XC 47 82473C 11R473C 4.7 NMH4809XC 47 82473C 11R473C 2.2 NMH4812XC 150 82154C 11R154C 3.3 NMH4815XC 100 82104C 11R104C 3.3 www.murata-ps.com/support KDC_NMH.F03 Page 5 of 8
