A signal control circuit and a switching apparatus are provided. The switching apparatus includes: a switch for controlling a current flowing through an inductive element; a monitoring node connected with the switch; and a signal control circuit, connected with the monitoring node and a reference voltage, for turning on/off the switch, wherein the signal control circuit includes an integrator for generating a comparison voltage by using a monitoring voltage of the monitoring node and the reference voltage, wherein the integrator includes: a resistor unit; a capacitor unit; and an auto-calibrator for receiving at least one selection signal and determining at least one of a resistance of the resistor unit and a capacitance of the capacitor unit, during a power-up period, and allowing a peak value of the comparison voltage to fall within a target range.
