RECOMMENDED CIRCUIT
All the CTDD3220DF-S1.5K-3
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). If you want to
use
the products in high EMI, please choose
our metal package products.
