1. When open or high impedance, the converter works well; when this
pin is 'high', the converter shuts down. It should be noted 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 works at perfect operation status, a full
loading external capacitor is necessary and it is recommended to use a
high frequency low resistance electrolytic capacitor.
