DESCRIPTION
The MEE1 series is the new high performance
version of our 1W NME series. The MEE1 series
is more efficient and offers improved regulation
performance for applications where a wide output
voltage variation can not be tolerated. They are
ideally suited for providing local supplies on
control system boards with the added benefit
of 1kVDC galvanic isolation to reduce switching
noise.

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 MEE1 series of DC-DC converters are all 100% production
tested at their stated isolation voltage. This is 1kVDC for 1 second.
A question commonly asked is, “What is the continuous voltage that can be applied
across the part in normal operation?”
The MEE1 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 off-
set 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 materi-
als, construction and environment. The MEE1 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 test-
ing, but if it is absolutely required, that the voltage be reduced by 20% from specified
test voltage.
This consideration equally applies to agency recognizsed 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 MEE1 series has been recognised by Underwriters Laboratory (UL) to UL 60950 for functional insulation in a maximum ambient temperature for 3.3V & 5V input models of
60°C and for 12V, 15V and 24V models of 85°C. File number E151252 applies. The MEE1 Series of converters are 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.
MEE1S03xxxC: 1A
MEE1S05xxxC: 0.7A
MEE1S12xxxC: 0.2A
MEE1S15xxxC: 0.2A
MEE1S24xxxC: 0.16A
All fuses should be UL approved and rated to at least the maximum allowable DC input voltage.
UL file number E151252 applies.
RoHS COMPLIANCE INFORMATION
This series is compatible with RoHS soldering systems with a peak wave solder temperature of 260°C for 10 seconds. The pin
termination finish on the SIP package type is Tin Plate, Hot Dipped over Matte Tin with Nickel Preplate. The DIP types are Matte
Tin over Nickel Preplate. Both types in this series are backward compatible with Sn/Pb soldering systems.

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 1.5 times 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.
Ripple & Noise Characterisation Method
Ripple and noise measurements are performed with the following test configuration.
C1 1µF X7R m ultilayer ceramic capacitor, voltage rating to be a minimum of 3 times the output voltage of the DC-DC converter
C2 10µF tantalum capacitor, voltage rating to be a minimum of 1.5 times the output voltage of the DC-DC converter with an ESR of less
than 100m at 100kHz
C3 100nF multilayer ceramic capacitor, general purpose
R1 450 resistor, carbon film, ±1% tolerance
R2 50 BNC termination
T1 3T of the coax cable through a ferrite toroid
RLOAD Resistive load to the maximum power rating of the DC-DC converter. Connections should be made via twisted wires
Measured values are multiplied by 10 to obtain the specified values.

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.
