APPLICATIONS
The F_M-1W & F_N-1W Series is 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
≤3000VDC);
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.

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, or
use our company’s products with a lower rated
output power.
Recommended circuit
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).

*Test ripple and noise by

of Power Converter section, application notes.
Note:
1. All specifications measured at T

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
recommended capacitance of its filter capacitor
sees (Table 1).
