CTRL Terminal
When open or high impedance,the converter work well; When this pin is ‘high’; the converter shutdown; It should be note that the
input current (Ic) should between 5-10mA, exceeding the maximum 20mA will cause permanence damage to the converter. The value
of R Can be derived as follows :
IC
Recommended Circuit
If you want to further decrease the input/output ripple, an “LC” filtering network may be connected to the input and output ends of
the DC/DC converter, see (Figure 1).

However, the capacitance of the output filter capacitor must be proper. If the capacitance is too big, a startup problem might arise.
For every channel of output, provided the safe and reliable operation is ensured, the greatest capacitance of its filter capacitor sees
