Murata Power Solutions NCM6 series of DC-DC converters are all 100% production tested at their stated isolation voltage. This is 5.2kVDC for 1 second. A question commonly asked is, “What is the continuous voltage that can be applied across the part in normal operation?” The NCM6 series has been recognised by Underwriters Laboratory to 250Vrms for Reinforced Insulation. 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. 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. SAFETY APPROVAL ANSI/AAMI ES60601-1 The NCM6 series has been recognised by Underwriters Laboratory (UL) to ANSI/AAMI ES60601-1 and provides 1 MOPP (Means Of Patient Protection) and 2 MOOP (Means Of Operator Protection) based upon a working voltage of 250 Vrms max., between Primary and Secondary. File number E202895 applies. UL 60950 The NCM6 series has been recognised by Underwriters Laboratory (UL) to UL 60950 for reinforced insulation to a working voltage of 250Vrms. File number E151252 applies. FUSING The NCM6 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. Input Voltage, 5V 3A Input Voltage, 12V 2A Input Voltage, 48V 1A All fuses should be UL recognised and rated to at least the maximum allowable DC input voltage. RoHS COMPLIANCE INFORMATION This series is compatible with RoHS soldering systems with a peak wave solder temperature of 260ºC for 10 seconds. Please refer to application notes for further information. The pin termination finish on this product series is a Gold flash (0.05-0.10 micron) over Nickel Preplate. The series is backward compatible with Sn/Pb soldering systems.

Between 0% and 10% output loading, the output voltage will remain within data sheet specification however, output ripple and noise may increase but will still be below 150mV p-p. www.murata.com KDC_NCM6C.I01 Page 8 of 23 NCM6 Series Isolated 6W Wide Input Single & Dual Output DC-DC Converters EFFIECIENCY VS LOAD NCM6D0505C NCM6D0512C 90% 85% 85% 80% Efficiency (%) Efficiency (%) 80% 4.5V 75% 5V 9V 4.5V 75% 5V 9V 70% 70% 65% 65% 10% 20% 30% 40% 50% 60% 70% 80% 90% 60% 10% 100% 20% 30% 40% 50% Load (%) 60% 70% 80% 90% 100% Load (%) NCM6D0515C NCM6S0503C 80% 85% 75% Efficiency (%) Efficiency (%) 80% 75% 70% 70% 4.5V 5V 65% 9V 60% 65% 55% 10% 60% 10% 20% 30% 40% 50% 60% 70% 80% 90% 20% 30% 40% 50% 60% 70% 80% 90% 100% Load (%) 100% Load (%) NCM6S0505C NCM6S0512C 85% 85% 80% 75% 4.5V 5V 70% 9V Efficiency (%) Efficiency (%) 80% 75% 4.5V 5V 70% 9V 65% 65% 60% 10% 60% 10% 20% 30% 40% 50% 60% 70% 80% 90% 20% 30% 40% 100% 50% 60% 70% 80% 90% 100% Load (%) Load (%) NCM6S0515C NCM6D1205C 85% 90% 85% 80% 80% 4.5V 5V 70% 9V Efficiency (%) Efficiency (%) 75% 75% 70% 9V 65% 12V 24V 60% 36V 55% 65% 50% 45% 60% 10% 20% 30% 40% 50% 60% Load (%) 70% 80% 90% 100% 40% 10% 20% 30% 40% 50% 60% 70% 80% 90% 100% Load (%) www.murata.com KDC_NCM6C.I01 Page 9 of 23 NCM6 Series Isolated 6W Wide Input Single & Dual Output DC-DC Converters EFFIECIENCY VS LOAD (Continued) NCM6D1212C NCM6D1215C 95% 90% 85% 85% 80% 75% 9V 65% 12V 24V 36V 55% 70% Efficiency (%) Efficiency (%) 75% 9V 65% 12V 24V 60% 36V 55% 50% 45% 45% 35% 10% 20% 30% 40% 50% 60% 70% 80% 90% 40% 10% 100% 20% 30% 40% 50% Load (%) NCM6S1203C 85% 80% 80% 70% 75% 9V 12V 40% 24V 36V 30% 90% 100% 65% 45% 40% 50% 60% 70% 80% 90% 24V 36V 50% 30% 12V 55% 10% 20% 9V 60% 20% 40% 10% 100% 20% 30% 40% 50% Load (%) 60% 70% 80% 90% 100% Load (%) NCM6S1212C NCM6S1215C 90% 90% 85% 85% 80% 80% 75% 75% 70% 9V 65% 12V 24V 60% 36V 55% Efficiency (%) Efficiency (%) 80% 70% 50% Efficiency (%) Efficiency (%) 60% 50% 70% 9V 65% 12V 24V 60% 36V 55% 50% 45% 40% 10% 70% NCM6S1205C 90% 0% 10% 60% Load (%) 45% 20% 30% 40% 50% 60% 70% 80% 90% 40% 10% 100% 20% 30% 40% Load (%) 50% 60% 70% 80% 90% 100% Load (%) NCM6D4805C NCM6D4812C 95% 85% 80% 85% 75% 70% 18V 60% 48V 24V 55% 75V Efficiency (%) Efficiency (%) 75% 65% 18V 65% 48V 24V 75V 55% 50% 45% 45% 40% 35% 10% 20% 30% 40% 50% 60% Load (%) 70% 80% 90% 100% 35% 10% 20% 30% 40% 50% 60% 70% 80% 90% 100% Load (%) www.murata.com KDC_NCM6C.I01 Page 10 of 23 NCM6 Series Isolated 6W Wide Input Single & Dual Output DC-DC Converters EFFIECIENCY VS LOAD (Continued) NCM6D4815C NCM6S4803C 80% 95% 75% 85% 70% 65% 18V 65% 48V 24V 75V 55% Efficiency (%) Efficiency (%) 75% 60% 18V 55% 24V 48V 50% 75V 45% 40% 45% 35% 35% 10% 20% 30% 40% 50% 60% 70% 80% 90% 30% 10% 100% 20% 30% 40% Load (%) 60% 70% 80% 90% 100% Load (%) NCM6S4805C NCM6S4812C 90% 90% 80% 80% 70% 18V 60% 24V 48V 75V 50% Efficiency (%) Efficiency (%) 70% 18V 60% 24V 48V 75V 50% 40% 40% 30% 10% 50% 20% 30% 40% 50% 60% 70% 80% 90% 30% 10% 100% Load (%) 20% 30% 40% 50% 60% 70% 80% 90% 100% Load (%) NCM6S4815C 90% 80% Efficiency (%) 70% 18V 60% 24V 48V 75V 50% 40% 30% 10% 20% 30% 40% 50% 60% 70% 80% 90% 100% Load (%) www.murata.com KDC_NCM6C.I01 Page 11 of 23 NCM6 Series Isolated 6W Wide Input Single & Dual Output DC-DC Converters TEMPERATURE DERATING (Continued) NCM6S1203C 6 5 5 4 still air 3 100 lfm 200 lfm 2 Power (W) Power (W) NCM6S0503C 6 400 lfm 1 4 still air 3 100 lfm 200 lfm 2 400 lfm 1 0 0 -40 -40 -30 -20 -10 0 10 20 30 40 50 60 70 80 (OC) Ambient Temperature -20 0 20 40 60 Ambient Temperature NCM6S4803C 80 (OC) NCM6X0505C 6 6 4 still air 3 100 lfm 200 lfm 2 5 Power (W) Power (W) 5 4 still air 100 lfm 3 200 lfm 2 400 lfm 1 400 lfm 1 0 0 -40 -20 0 20 40 60 -40 80 Ambient Temperature -20 0 20 NCM6X0512C 80 4 still air 100 lfm 3 200 lfm 2 Power (W) 6 5 Power (W) 60 (OC) NCM6X0515C 6 5 4 still air 100 lfm 3 200 lfm 2 400 lfm 1 400 lfm 1 0 0 -40 -20 0 20 40 60 -40 80 Ambient Temperature (OC) -20 0 20 40 60 80 Ambient Temperature (OC) NCM6X1205C NCM6X1212C 6 5 still air 4 100 lfm 3 200 lfm 2 400 lfm Power (W) 6 Power (W) 40 Ambient Temperature (OC 5 4 still air 100 lfm 3 200 lfm 2 400 lfm 1 1 0 0 -40 -20 0 20 40 60 Ambient Temperature (OC) 80 -40 -20 0 20 40 60 80 Ambient Temperature (OC) www.murata.com KDC_NCM6C.I01 Page 12 of 23 NCM6 Series Isolated 6W Wide Input Single & Dual Output DC-DC Converters TEMPERATURE DERATING (Continued) NCM6X1215C NCM6X4805C 6 Power (W) 5 still air 4 100 lfm 3 200 lfm 2 Power (W) 6 5 4 still air 100 lfm 3 200 lfm 2 400 lfm 1 400 lfm 1 0 0 -40 -20 0 20 40 60 80 -40 -20 0 NCM6X4812C 40 60 80 NCM6X4815C 6 5 4 still air 100 lfm 3 200 lfm 2 400 lfm Power (W) 6 Power (W) 20 Ambient Temperature (OC) Ambient Temperature (OC) 5 4 still air 100 lfm 3 200 lfm 2 400 lfm 1 1 0 0 -40 -20 0 20 40 Ambient Temperature 60 (OC) 80 -40 -20 0 20 40 60 80 Ambient Temperature (OC) EMC FILTERING AND SPECTRA FILTERING The module includes a basic level of filtering, sufficient for many applications. Where lower noise levels are desired, filters can easily be added to achieve any required noise performance. A DC-DC converter generates noise in two principle forms: that which is radiated from its body and that conducted on its external connections. There are three separate modes of conducted noise: input differential, output differential and input-output. This last appears as common mode at the input and the output, and cannot therefore be removed by filtering at the input or output alone. The first level of filtering is to connect capacitors between input and output returns, to reduce this form of noise. It typically contains high harmonics of the switching frequency, which tend to appear as spikes on surrounding circuits. The voltage rating of this capacitor must match the required isolation voltage. (Due to the great variety in isolation voltage and required noise performance, this capacitor has not been included within the converter.) Input ripple is a voltage developed across the internal Input decoupling capacitor. It is therefore measured with a defined supply source impedance. Although simple series inductance will provide filtering, on its own it can degrade the stability. A shunt capacitor is therefore recommended across the converter input terminals, so that it is fed from a low impedance. If no filtering is required, the inductance of long supply wiring could also cause a problem, requiring an input decoupling capacitor for stability. An electrolytic will perform well in these situations. The input-output filtering is performed by the common-mode choke on the primary. This could be placed on the output, but would then degrade the regulation and produce less benefit for a given size, cost, and power loss. Radiated noise is present in magnetic and electrostatic forms. Thanks to the small size of these units, neither form of noise will be radiated “efficiently”, so will not normally cause a problem. Any question of this kind usually better repays attention to conducted signals. www.murata.com KDC_NCM6C.I01 Page 13 of 23 NCM6 Series Isolated 6W Wide Input Single & Dual Output DC-DC Converters EMC FILTERING AND SPECTRA (Continued) EMC FILTER AND VALUES TO OBTAIN SPECTRA AS SHOWN The following filter circuit and filter table shows the input filters typically required to meet EN55022 Quasi-PeakCurve A or B.
