PIN CONNECTIONS
CS Pin
By connecting a low ESR capacitor between this terminal and the pin-7 (connection to the anode of the capacitor),
the output ripple and noise may be further improved. Generally, the capacitance is no greater than 100µF.
CTRL
When open or high impedance, converter work well. When control pin positive referenced to the negative input (equal
to import to earth), converter shutdown. Please note that the input current should be between 5-10mA, exeeding the
maximum 20mA will cause permanent damage to converter.

RECOMMENDED CIRCUIT
All the CTDD2210SF-S1.5K-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 1). If you want to
use
the products in high EMI, please choose our metal
packaged products.
