1、 According to UCD3138HSFBEVM-029 manual, in order to achieve the current sharing function, AD02 pin should output a voltage according to output current. At the same time AD02 pin also need to read the Isharebus voltage, and compare this two voltage value, in order to achieve the current sharing function. But how AD02 pin to output voltage and read the Ishare bus voltage at the same time?
2、 I would like to ask if the current share pin on the primary side, UCD3138 on the secondary side, how to realize the current share function?
