APPLICATIONS
The IF_S(D)-1W Series are specially designed
for applications where a single power supply is
highly 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
≤3000VDC);
3) Where the regulation of the output voltage
and
the
output
ripple
and
noise
are
demanding.

APPLICATION NOTE
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, 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 (IF_S(D)
–W25
Series).
Filtering
*
Supply voltage must be discontinued at the end of short circuit duration.
TYPICAL CHARECTERISTICS
Temperature Derating Graph
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
(Table 1).

It’s not recommended to connect any external capacitor
in the application field with less than 0.5 watt output.
To get an extrem ely 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 (Figure 1).

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.
