*Supply voltage must be discontinued at the end of short circuit duration.
The D-XNM-1W Series are specially designed
for applications where a group of polar power
supplies are isolated from the input power
supply in a distributed power supply system on a
circuit board.
These products apply to:
1) Where the voltage of the input power supply
is fixed (voltage variation ≤±10%);
2) Where isolation is necessary between input
and output (isolation voltage ≤1000VDC);
3) Where the regulation of the output voltage
and the output ripple noise are not demanding.
Such as:purely digital circuits, ordinary low
frequency analog circuits,and IGBT power
device driving circuits.

RECOMMENDED CIRCUIT
APPLICATION NOTE
Requirement on output load
To ensure
this module can operate efficiently and reliably, During operation, the minimum output
load could not be less than 10% of the full load . If the actual output power is very small , please
connect
a
resistor
with
load , or use our company proper
resistance
at
the
output
end
in
parallel
to increase the
products with a lower rated output power.
Recommended circuit
If
you want
to
further
decrease
the
input/output
ripple , an "LC"
filtering
network may
be connected to the input and output ends of the DC/DC converter, see (Figure 1).
It should also be noted that the
be staggered with
inductance and the frequency of the "LC" filtering network should
the DC/DC frequency to avoid mutual
the output filter capacitor must be proper. If
interference. However , the capacitance
the capacitance is too big , a startup
of
problem might arise.
For every channel of output , provided the safe and reliable operation is ensured , the recommended
capacitance of its filter capacitor sees (Table 1).
Output Voltage Regulation and Over-voltage Protection Circuit
The simplest device for output voltage regulation, over-voltage and over-current protection is a linear
voltage regulator with overheat protection that is connected to the input or output end in series (Figure 2).
Overload Protection
Under normal operating conditions,
overload . The
simplest method
is
the output circuit of
to
connect
a
these products has no protection against
self-recovery
fuse
in
series
at
the input
end or add a circuit breaker to the circuit.
No parallel connection or plug and play
It's not
recommended
capacitor in
to connect
any
external
the application field with less
than 0.5
watt output.

RoHS COMPLIANT INFORMATION
This series is compatible with RoHS soldering systems with a peak wave solder temperature
of 300°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.
