Zusammenfassung:	A control device serves as an agent that controls a switching regulator including an output switch and a synchronous rectification switch. The control device includes: a summator generating a sum sense signal by adding up a first sense signal commensurate with the current passing in the output switch and a second sense signal commensurate with the current passing in the synchronous rectification switch; a smoother generating a smoothed sense signal by smoothing the sum sense signal; and a switch driver driving the output switch and the synchronous rectification switch complementarily through current mode control based on the smoothed sense signal.
