APPLICATIONS
The IB_XLS-1W & IB_XLD-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 demanded.

Requirement on output load
To ensure this module can operate efficiently and
reliably, During operation,the minimum output load is not
less than 10% of the full load,and that this product
should never be operated under no 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's products with
a lower rated output power(IB_XLD -W25/IB_XLS-W25
series).
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).
*Supply voltage must be discontinued at the end of short circuit duration.
TYPICAL CHARACTERISTICS
Temperature Derating Graph
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).

It's not recommend 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 over-current
and short-circuits.The simplest method is to connect a
self-recovery fuse in series at the input end or add a
circuit breaker to the circuit.
When the environment temperature is higher than
71 C, the product output power should be less then
71°C,
60% of the rated power.
No parallel connection or plug and play.
Use dual output simultaneously, forbid opening output
pin(0V)to use as single 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.
