Beschreibung
Zusammenfassung:	In the present invention, disclosed is a switching power supply apparatus. The switching power supply apparatus includes: a switch for regulating a current of an inductor; and a control unit which measures a time until a monitoring voltage corresponding to the current of the inductor reaches a specific voltage, from a turn-on point of the switch, corrects a turn-off point of the switch by using the time, and controls the switch. Accordingly, the present invention can regulate an average current of the inductor to a target average current. 본 발명은 스위칭 전원 공급 장치를 개시한다. 상기 스위칭 전원 공급 장치는, 인덕터의 전류를 레귤레이션하기 위한 스위치; 및 상기 스위치의 턴온 시점부터 상기 인덕터의 전류에 대응하는 모니터링 전압이 특정전압에 도달할 때까지의 시간을 측정하고, 상기 시간을 이용하여 상기 스위치의 턴오프 시점을 보정하며, 상기 스위치를 제어하는 제어부;를 포함한다.
