NXE1 Series  
Isolated 1W Single Output SM 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 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 recognized 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 recognized 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.  
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 recognized 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.

TOLERANCE ENVELOPES  
The voltage tolerance envelopes show typical load regulation characteristics for this product series. The tolerance envelope is the maximum output voltage variation due to  
changes in output loading and set point accuracy.

NXE1 Series  
Isolated 1W Single Output SM DC/DC Converters  
APPLICATION NOTES  
Short Circuit Performance  
NXE1 series offers short circuit protection which is continious with nominal input voltage at low ambient temperatures. 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  
are fully dried before input power application.  
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 & 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.

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.
