package. With a new package design these
converters are qualified for the higher
temperatures requested by lead-free reflow
solder processes. With the small footprint,
these converters are the ideal solution for
board level power distribution,mainly for
applications in the industrial and telecom field.

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 speciffi
ed time, across a component designed to provide electrical isolation, to verify the integrity of that isolation.
Professional Power Module NTE-X 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 speciffic agency approvals, such as the NTE-X 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 NTE-X 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 speciffied 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.

NTE-X Series
Application Notes
Minimum load
The minimum load to meet data sheet speciffication is 10% of the full rated load across the speciffied input voltage range. Lower than 10% minimum loading will result in an
increase in output voltage, which may rise to typically double the speciffied 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.

NTE-X Series
Application Notes
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.
