RECOMMENDED CIRCUIT
All the CTDD5025DF-S1K-10M
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). When it is
used
in
unregulated
power
supply, be sure
that the flucuating range of the power
supply adn
the rippled voltage do not exceed the
module
standard.
Input current of power
supply should afford
the
startup
current of this kind of DC/DC module. (See figure 2)
