RECOMMENDED CIRCUIT
All the CTDD2709SF-T1K-1
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). 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 2). If you want to
use
the products in high EMI, please choose our metal packaged
products.
