APPLICATIONS
The D_N-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
≤±
10%);
2) Where isolation is necessary between input
and output (isolation voltage =1000VDC);
3) Where the regulation of the output voltage
and the output ripple and noise are not
demanding.
Such as: purely digital circuits, ordinary low
frequency analog circuits and IGBT power
device driven circuits, etc.
These products don’t apply to:
1) Where the input supply voltage is varied
(variation
≥±
10%), otherwise our company’s
WRA series is recommended;
2) Where the isolation voltage between input
and output is required to be
>
1000VDC,
otherwise our company’s ED Series of
products are recommended;
3) Circuits in which the output voltage
regulation is demanding, otherwise our
company’s IF Series or WRF Series are
recommended;
4) The output load’s actual power
consumption is less than 0.25W, otherwise
our company’s D_N-0.25W Series are
recommended.
Note: here
Io1and Io2 are corresponded with Vo1and Vo2
.

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.

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 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 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!
