Murata Power Solutions NXE1 series of DC-DC converters are all 100% production tested at 3kVDC for 1 second and have been qualification tested at 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 NXE1 series has been recognised by Underwriters Laboratory to 125 Vrms Reinforced Insulation and 250Vrms Basic insulation, please see safety approval section below. 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 NXE1 series has a PCB embedded isolated transformer, using FR4 as an insolation barrier between primary and secondary windings. While parts can be expected to withstand several times the stated test voltage, the isolation capability does depend on the FR4 insulation properties. Any material, including FR4 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 should be reduced by 20% from specified test voltage. This consideration equally applies to agency recognised parts rated for better than functional isolation where the insulation is always supplemented by a further insulation system of physical spacing or barriers. SAFETY APPROVAL ANSI/AAMI ES60601-1 The NXE1 series is recognised by Underwriters Laboratory (UL) to ANSI/AAMI ES60601-1 and provides 1 MOOP (Means Of Operator Protection) based upon a working voltage of 250 Vrms max, between Primary and Secondary. UL 60950 The NXE1 series has been recognised by Underwriters Laboratory (UL) to UL 60950 for reinforced insulation to a working voltage of 125 Vrms and for basic insulation to a working voltage of 250Vrms. Creepage is 2.5mm and clearance is 2mm FUSING The NXE1 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, 3.3V: 1A Input Voltage, 5V: 0.5A All fuses should be UL recognised and rated to at least the maximum allowable DC input voltage. RoHS COMPLIANCE AND MSL INFORMATION This series is compatible with Pb-Free soldering systems and is also backward compatible with Sn/Pb soldering systems. The NXE1 series can be soldered in accordance with J-STD-020 and have a classification temperature of 260°C and moisture sensitivity level 2. The termination finish on this product is Gold with plating thickness 0.12 microns. www.murata-ps.com All enquiries: www.murata-ps.com/support KDC_NXE1.E04 Page 2 of 8 NXE1 Series Isolated 1W Single Output SM DC-DC Converters TOLERANCE ENVELOPES The voltage tolerance envelopes show typical load regulation characteristics for this product series.

At higher ambient temperatures of 65 °C and above short circuit duration will be limited. Advisory Notes Minimum Load The NXE1 series is not hermetically sealed, customers should ensure that parts The minimum load to meet datasheet specification is 10% of the full rated load are fully dried before input power application. 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 & 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. Typical Start-Up Wave Form Start-up time µS NXE1S0303MC 150 NXE1S0305MC 400 NXE1S0505MC 250 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.
