Overload Protection When open or high impedance, the converter work well; When this pin is high,t he converter shut down; It should be note that the input current should between 5-10mA,exceeding the maximum 20mA will cause permanence damage to the converter. The value of R can be derived as follows: 3. Remote On/Off (CTRL Terminal) R VDVC 1.0 IC Reduce output ripple, it is recommended to use capacitors at the input/output.
