  • Publication number: 20230016211
    Abstract: A switch control circuit and a switch control method are provided. The switch control circuit includes a load, an inductor, a control switch, and a sensing resistance connected in series to an input power; an integrator that integrates a sensing voltage and a load current setting voltage to generate an integrated signal; a comparator that compares the integrated signal and a bias voltage; a switch driver that controls the control switch based on an output of the comparator and an output of an off time controller; and a gate sensor that outputs, to the integrator, a gate sensing signal that senses a time when an input of a gate terminal of the control switch becomes a low level. An integration operation is started from a position in which the integrated signal is located lower than the bias voltage, when an input of the gate terminal becomes a high level.
