The FB_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 ≤5200VDC);
3) Where the regulation of the output voltage
and the output ripple noise are not
demanding.
Such as: purely digital circuits, ordinary low
frequency analog circuits, and IGBT power
device driving circuits.

OUTPUT SPECIFICATIONS
If you want to further decrease the
input/output ripple, an “LC” filtering network may
be connected to the input and output ends of the
DC/DC converter, see (Figure 1).

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. 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
(Table 1).

Overload Protection
Under normal operating conditions, the output
circuit of these products has no protection
against overload. 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
Requirement on output load
To ensure this module can operate efficiently and reliably, During operation, 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.
