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. 27DW - 24 S 05 R NL A B C D E F A : Series B : Input Voltage C : Single Output D : Output Voltage E : Regulated(R) F : RoHS Version Packaging Size(mm) A B C D 12.0 28.55 550 6.00
