  • Patent number: 11955887
    Abstract: A switch control circuit and a switch control method are provided. In this circuit, compositions that sense a drain voltage of a switch device are added in a QR Buck Converter switch control circuit. A first resistor, a second switch, a second resistor are electrically connected to a drain terminal of a switch device to sense the 0 A state of an inductor current. On the basis of a detection result, the switch control circuit turns on the switch device when an inductor current is 0 A, and a drain sensing voltage (ZCD) is less than a predetermined reference voltage (REF).
