DESCRIPTION
67
The NMF series of DC/DC converters is used
where a tightly regulated supply is required. They
are ideal for situations where the intput voltage is
not tightly controlled. The output trim pin makes
the device particularly suitable for applications
requiring a programmable output voltage. The 5V
output version can be used to give a regulated
output, adjustable between 1.2V and 5.0V with a
single resistor. An option not to have this function
is available, on SIP package type parts, prefix C
with N. The single rail regulated output makes the
ideal choice to power sensors, such as pressure
transducers, hall effect sensors and mass airflow
sensors.
When operated with additional external load capacitance the rise time of the input voltage will determine the maximum external
capacitance value for guaranteed start up. The slower the rise time of the input voltage the greater the maximum value of the
additional external capacitance for reliable start up.

RoHS COMPLIANCE INFORMATION
This series is compatible with RoHS soldering
systems with a peak wave solder temperature of
300ºC for 10 seconds. The pin termination finish
on the SIP package type is Tin Plate, Hot Dipped
over Matte Tin over Nickel Preplate. The DIP
types are Matte Tin over Nickel Preplate. Both
types in this series are backward compatible
with Sn/Pb soldering systems.

OUTPUT VOLTAGE ADJUSTMENT (for 5V output variants)
The trimming (adjust) input on the device allows output voltage adjustment from 1.2V to 3.3VDC by using a resistor as shown here. The table below provides RTRIM values for the
most commonly required output voltages. For applications not requiring the TRIM function, this pin must be left unconnected for normal regulated output.

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 NMF 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?”
For a part holding no specific agency approvals, such as the NMF series, 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 NMF series has toroidal isolation transformers, with no additional insulation between primary and secondary windings of enameled 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 recognized 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.
