The synchronous rectification circuit is self-driven by a combination of a charge pump and a Boost circuit, including a rectification MOSFET, a charge pump, logic control modules, voltage detection modules, an oscillator module, a PWM generation module, a reference voltage generation module, a switch, a free-wheeling MOSFET, an isolation MOSFET, an inductor, a capacitor and sampling resistors. According to the present application, initially, the charge is stored on the capacitor through the charge pump, the Boost circuit is turned on till the voltage is increased to a certain value; through processing by the logic control modules and the like, the rectification MOSFET is turned on, thus self-driving of the synchronous rectification circuit is achieved. The self-driving mode can charge the capacitor faster, lower the duty of the rectification circuit, and reduce the average conduction voltage drop."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Synchronous rectification circuit","description":"Provided is a synchronous rectification circuit, which relates to electronic circuit technologies.
