Parameter Voltage range Input short circuit current Input reflected ripple current DESCRIPTION The CMR series are a cost effective 0.75W DC-DC converter series, in an industry standard package with industry standard pinouts, Popular input and output voltages are available as a lower power alternative to a 1W DC-DC converter. The galvanic isolation allows the device to be configured to provide an isolated negative rail in systems where only positive rails exist. The wide temperature range guarantees startup from –40°C and full 0.75 watt output at 85°C. For the short circuit protected parts (PC) protection is continuous and auto-resetting on removal of the short circuit. MTTF1 5 24 Isolation Capacitance CMR100C CMR118C mV p-p % Typ. Max Typ. Max.

Murata Power Solutions CMR series of DC-DC converters are all 100% production tested at their stated isolation voltage. This is 1kVDC for 1 second for C versions and 3kVDC for 1 minute for 3C versions. A question commonly asked is, “What is the continuous voltage that can be applied across the part in normal operation?” The CMR is 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 CMR 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 UL60950 The CMR is recognised by Underwriters Laboratory (UL) to UL 60950 for functional insulation. The CMR100C and CMR118C in a maximum still air ambient temperature of 100°C as measured at any point on the case of the unit (hotspot). FUSING The CMR Series of converters are not internally fused so to meet the requirements of UL an anti-surge input line fuse should always be used with ratings as defined below. CMR100xC: 0.5A CMR118C: 0.12A CMR05xxxx3C: 0.315A CMR12xxxx3C: 1A All fuses should be UL recognised and rated to 125V. File number E151252 applies.

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 20MHz.
