Markings and dimensions
1. When open or high impedance, the converter works well;
when this pin is 'high', the converter shut down. It should be
note that the input current should be between 5-10mA,
exceeding the maximum 20mA will cause permanent damage
to the converter.
2. To make sure the product work at perfect operation status
with full loading external capacitor is necessary and it is
recommended to use high frequency low resistance
electrolytic capacitor.
