Abstract
A driving circuit for driving a synchronous rectifier device. The driving circuit may include a controllable charging circuit and a slope sensing circuit. The slope sensing circuit may sense whether an abrupt rising change in a voltage drop from a sensing terminal to a reference ground terminal of the driving circuit is occurring, and provide a slope sensing signal in response to a rising edge of the abrupt rising change in the voltage drop. The controllable charging circuit may receive the slope sensing signal and provide a charging current to a supply terminal of the driving circuit in response to each rising edge of the abrupt rising change in the voltage drop.
