Abstract
A power receiving unit includes a hysteresis comparator, includes a comparison voltage based on an output voltage at an output terminal and a first reference voltage and outputs a comparison result signal responsive to a result of the comparison. The power receiving unit includes a current operational amplifier that receives a converted voltage based on a current flowing through an output transistor and a preset second reference voltage and outputs a current error signal responsive to the difference between the converted voltage and the second reference voltage. The power receiving unit includes a first multiplexer that receives the current error signal and the comparison result signal, selects either of the comparison result signal and the current error signal based on the comparison result signal and outputs the selected signal. The output transistor is controlled based on a first output signal selected by the first multiplexer.
