A first current source is used for providing a preset current ISUM equal to a sum of the off current value IOFF and the blanking current value ILEB to charge a first capacitor, and a second current source is used for providing a reference current IREF to charge a second capacitor. A comparator receives a voltage applied on the first capacitor at its positive input end and a voltage applied on the second capacitor at its negative input end. The output current transmitted to the load by the flyback converter is varied to the change of the preset current ISUM, as such the load condition is detected by the comparison result generated by the comparator."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Circuit and method for evaluation overload condition in flyback converter","description":"A circuit and a method for evaluating a load condition in a flyback converter are disclosed.
