Abstract
The interleaved switching converter circuit of the present invention includes: a first and a second switching converter which are connected in parallel to each other; a first control driver for turning ON/OFF the first switching converter; a charger/discharger having a first and a second capacitor and alternately charging/discharging the first and the second capacitors, in response to the turn ON/OFF of the first switching converter; and a second control driver for turning ON/OFF the second switching converter in synchronism with an inversion of a difference between voltages of the first and the second capacitors.
