Max. 88 kHz PRODUCT OVERVIEW TEMPERATURE CHARACTERISTICS The MMV1S series of DC-DC converters are a high efficiency version of the popular NMV series but with guaranteed short circuit protection across the operating temperature range. Short circuits of less than 1Ω cause the converter to enter a ‘foldback’ limiting mode such that the the input current is approximately 100mA for 0505 variant and 45mA for 0524 variant. Protection is continuous and auto-resetting on removal of the short circuit. Parameter Conditions Min.

Murata Power Solutions MMV1 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 MMV1 has been recognised 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 MMV1 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. SAFETY APPROVAL The MMV1 has been recognised 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 of 155ºC (case temperature measured on the face opposite the pins). The MMV1 converter is 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. MMV1S0505SC: 0.375A MMV1S0524SC: 0.4A The fuses should be UL recognised and rated to at least the maximum allowable DC input voltage. File number E151252 applies.

C2 Differential Mode Noise Test Schematic DC/DC Converter OSCILLOSCOPE C1 C2 C3 + SUPPLY Input - R1 + T1 R2 Y INPUT Output - R LOAD 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 1.25 times the specified output voltage if the output load falls to less than 5%. Capacitive loading and start up Typical start up time for the MMV1 series, with a typical input voltage rise time of 2.2μs and output capacitance of 10μF is 370μS for 0505 variant and 5.8mS for 0524 variant. 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 20MHz.
