APPLICATION NOTE
Recommended Circuit
All the VFA_MP-6W & VFB_MP-6W Series have
been
tested
according
testing
to
the
before
following
leaving
recommended
circuit
factory. This series should be tested under load.
Never be tested under no load (see Figure 1).

If you want to further decrease the output ripple,
you can increase capacitance properly or choose
capacitors
with
low
ESR.
However,
the
capacitance should not be too high (Table 1).
