The ON signal generating circuit provides an ON signal based on a reference signal and a feedback signal. The current sensing circuit provides a current sensing signal based on a current flowing through a power switch of the converter. The OFF signal generating circuit provides an OFF signal based on an OFF threshold signal and the current sensing signal. The logic circuit provides a control signal based on the ON signal and the OFF signal. The OFF threshold generating circuit adjusts the OFF threshold signal based on the difference between a frequency of the switching signal and a preset frequency, so as to make the frequency of the switching signal substantially equal or larger than the preset frequency."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Control circuit and associated method for switching converter","description":"A control circuit for switching converter has an ON signal generating circuit, a current sensing circuit, an OFF signal generating circuit, a logic circuit and an OFF threshold generating circuit.
