APPLICATIONS
The IA_XS-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.

TEMPERATURE CHARACTERISTICS
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).

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.

Input Over-voltage Protection Circuit
The simplest device for input over-voltage protection is
a linear voltage regulator with overheat protection that is
connected to the input end in series (Figure 2).

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.
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.
