A switching mode power supply apparatus comprising a tilt compensation circuit is disclosed. The tilt compensation circuit comprises a duty ratio detection portion and a tilt adjustment portion. The duty ratio portion detects a switching duty ratio of the switching mode power supply apparatus, and the tilt adjustment portion performs further tilt compensation when the duty ratio that is detected is high. As a result, the switching mode power supply apparatus in a current mode can maintain a quick response capability even at a low duty ratio, by means of performing different tilt compensations depending on the switching duty ratio. |
