RECOMMENDED CIRCUIT
All the CTDD3220DF-S1.5K-6M
Series
have
been
tested
according
to the following recommended testing circuit
before
leaving factory. This
series should be
tested
under
load. Never
be
tested
under
no load (See figure 1 & 2). If you want
to further decrease the input/output ripple, you can increase capacitance properly or choose capacitors with low ESR.
However, the capacitance
should
not
be
too high. (See table 1)
