Abstract
According to an embodiment, provided is a power circuit including: a switching transistor connected between an input terminal and an output terminal; a drive circuit configured to output a drive signal that controls on/off of the switching transistor; an error calculation circuit configured to output an error value between the output voltage and reference voltage; a determination circuit configured to compare a reference value obtained from the error value with a predetermined threshold value and then output a control signal; and a control circuit configured to control a frequency of the drive signal in response to the control signal.
