APPLICATIONS
The D-XM 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.

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 proper resistance at the output end in parallel to increase the load , or use our company
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 inductance and the frequency of the "LC" filtering network should be
staggered with the DC/DC frequency to avoid mutual interference. However , the capacitance of the output
filter capacitor must be proper. If the capacitance is too big,a startup 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).
It's not
recommended to connect any external capacitor in the
application field with less than 0.5 watt output.
Overload Protection
Under normal operating conditions, the output circuit of these products has no protection against
overload.The simplest method is to connect a self-recovery fuse in series at the input end or add a circuit
breaker to the circuit.
No parallel connection or plug and play
