APPLICATION NOTES
CTRL Terminal
When open or high impedance,the converter work well; When this pin is ‘high’; the converter shutdown; It should be noted that the
input current (Ic) should between 5-10mA, exceeding the maximum 20mA will cause permanent damage to the converter. The value
of R can be derived as follows :

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. To
ensure safe and reliable operation see Table 1 for the maximum capacitance of each channel of output.

While using unstable power source, please ensure the output voltage and ripple voltage do not excced indexes of the converter. The
preceding power source must be able to provide for converter sufficient starting current Ip.
