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.
