Abstract: Disclosed are a switching apparatus including an internal circuit using an inductive element and a control method thereof. The switching apparatus includes a switch that regulates a current of the inductive element, and a signal control circuit that arithmetically calculates a turn-off time point of the switch by using a monitoring voltage corresponding to the current of the inductive element, a sampling voltage of the monitoring voltage, and a reference voltage corresponding to a target average current of the inductive element, and controls the switch.

Abstract: 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.
