The flyback converter includes: a transformer circuit, a power switch circuit, a primary side control circuit, a synchronous rectification (SR) switch, and a synchronous rectification (SR) control circuit. When a feedback signal indicates that a difference between a target output voltage and an actual output voltage increases, the primary side control circuit increases an operation frequency of an operation signal by step-wisely reducing a cycle period of the operation signal in response to the increase of the difference, wherein the cycle period of the operation signal is reduced by a predetermined unit of time in each step, such that the cycle period of the operation signal is a step function of the increase of the difference."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Flyback converter operating by synchronous rectification with transient protection, primary side control circuit therein, and control method thereof","description":"The present invention discloses a flyback converter, a primary side control circuit therein, and a control method thereof.
