... VIPer12ADIP / VIPer12AS PIN FUNCTION Name Power supply of the control circuits. Also provides a charging current during start up thanks to a high voltage current source connected to the drain. For this purpose, an hysteresis comparator monitors the V voltage and provides two thresholds Voltage value (typically 14.5V) at which the device starts switching and turns off the start up ...
