APPLICATIONS
The IA_P-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
demanded;
These products don’t apply to:
1) Where the input supply voltage varied
otherwise
our
(variation
≥±
5%),
company’s WRA series is recommended;

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 extremely 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, and that this product should never be operated under no load!
