Package material
The IB-XT-1W&IB-NXT-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≤±5%);
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.

RECOMMENDED CIRCUIT
APPLICATION NOTE
1) 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.
2) Recommended testing 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 greatest capacitance of
its filter capacitor sees (Table 1).
3) Overload Protection
Under normal operating conditions, the output circuit of these products has no protection against
over-current . The simplest method is to connect a self-recovery fuse in series at the input end or add a
circuit breaker to the circuit .
4) When the environment temperature is higher than 71
71℃,, the product output power should be
less then 60% of the rated power
5) No parallel connection or plug and play
