The control circuit includes: a current comparing circuit that asserts a peak current sensing signal when a current flowing in the coil during the ON period of the switching transistor reaches a threshold current. The current comparing circuit includes: a first comparator that compares a sensed voltage according to the current flowing in the switching transistor and the coil with a threshold voltage defining the threshold current, and generates a comparison signal; and a variable delay circuit that generates the peak current sensing signal by delaying the comparison signal, a delay amount of the variable delay circuit varying according to a period of time from a turn-on of the switching transistor to a transition of the comparison signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Switching converter and control circuit thereof, current sensing method, AC/DC converter, and power adaptor and electronic devices","description":"A control circuit is used in a switching converter including at least, a switching transistor and a coil connected to the switching transistor.
