The IE_S-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

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.

APPLICATION NOTE
Filtering
In some circuits which are sensitive to noise and ripple, a filtering capacitor
may be added to the DC/DC output end and input end to reduce the noise and
ripple. However, the capacitance of the output filter capacitor must proper. If
the capacitance is too big, a startup problem might arise. For every channel of
output, providing the safe and reliable operation is ensured, the greatest
capacitance of its filter capacitor refer to the External Capacitor Table. To get
an extreme low ripple, an “LC” filtering network may be connected to the input
and output ends of the DC/DC converter, which may produce a more
significant filtering effect. 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 (see figure 1).
Requirement on output load
To ensure this module can operate efficiently and reliably, a minimum load is
specified for this kind of DC/DC converter in addition to a maximum load
(namely full load). During operation, make sure the specified range of input
voltage is not exceeded, the minimum output load is not less than 10% of the
full load, 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 (IE_S -0.25W series).
