APPLICATIONS
The IA_P-2W 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);

TYPICAL CHARACTERISTICS
Temperature Derating Graph
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).

Overload Protection
（
0.37）
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.

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!
