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.

PRODUCT OVERVIEW

The NTV series of 3kV isolation miniature

surface mounted DC/DC converters employ

leadframe technology and transfer moulding

techniques to bring all of the beneﬁts of IC style

packaging to hybrid circuitry. The co-planar-

ity of the pin positions is based upon IEC

191-6:1990. The devices are suitable for all

applications where high volume production is

envisaged.

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, ap-

plied for a speciﬁed time, across a component designed to provide electrical isolation, to verify the integrity of that isolation.

Murata Power Solutions NTV series of DC/DC converters are all 100% production tested at their stated isolation voltage. This is 3kVDC for 1 minute.

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 NTV 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 NTV 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 there-

fore 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 insula-

tion system of physical spacing or barriers.

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 double the speciﬁed output voltage if the output load falls to less than 5%.

RoHS COMPLIANCE, MSL AND PSL INFORMATION

This series is compatible with RoHS soldering systems and is also backward compatible with Sn/Pb soldering systems.

The NTV series has a process, moisture, and reﬂow sensitivity classiﬁcation of MSL1 PSL R7F as deﬁned in J-STD-020

and J-STD-075. This translates to: MSL1 = unlimited ﬂoor life, PSL R7F = Peak reﬂow temperature 245°C with a

limitation on the time above liquidus (217°C) which for this series is 60sec max. The pin termination ﬁnish on this product

series is Gold with a plating thickness of 0.05 microns minimum.
