  • Detection circuit, switching regulator having the same and control method
    Patent number: 10797580
    Abstract: A detection circuit for detecting an inductor current flowing through an inductor is provided. The inductor is coupled to a switch. The detection circuit includes a comparison circuit and a signal generating circuit. The comparison circuit, having a first node, is configured to compare a conduction time of a diode of the switch with a time threshold to provide a first voltage at the first node. The signal generating circuit, coupled to the first node, is configured to output a first detection signal according to the first voltage. The first detection signal indicates whether the inductor current flowing through the inductor reaches a first current threshold. A switching regulator comprises the detection circuit. A control method controls the switching regulator.
