APPLICATION NOTES
Requirement on Output Load
In order to ensure the product operates efficiently and reliably, make sure the specified range of input voltage is not exceeded and the
minimum output load is not less than 10% load. If the actual load is less than the specified minimum load, the output ripple may
increase sharply while its efficiency and reliability will reduce greatly. If the actual output power is very small, please add an
appropriate resistor as extra loading.

If you want to further decrease the input/output ripple, you can increase capacitance properly or choose capacitors with low ESR. If
the capacitance is too big, a startup problem might arise. The maximum allowable capacitance to ensure safe and reliable operation is
listed in Table 1.

Remote On/Off
When open or high impedance,the converter will be on; When this pin is ‘high’; the converter will shutdown; It should be noted that
the input current (Ic) should between 5 ~ 10 mA, exceeding the maximum 20 mA will cause permanent damage to the converter.
The value of R Can be derived as follows :
