The control circuit samples a valley value of an electric current through a first power transistor in a power stage circuit and a peak value of an electric current through a second power transistor in the power stage circuit, and obtains parameters representing an output current in accordance with an average value of the valley value and peak value. Thus, the constant-current control can be performed by sampling the electric current through the first power transistor and the second power transistor. Moreover, the switching power converter simplifies a current feedback loop for outputting a constant current, and the integrated circuit has fewer pins."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Switching power converter, control circuit and integrated circuit therefor, and constant-current control method","description":"The present disclosure relates to a switching power converter, a control circuit and an integrated circuit therefor, and a constant-current control method.
