  • Circuit with slope sensing for driving synchronous rectifier device
    Patent number: 11381151
    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.
    Type: Grant

  • Driving circuit allowing efficient turning-off of synchronous rectifiers
    Patent number: 10784791
    Abstract: A driving circuit and driving method for driving a synchronous rectifier. When a drain-source detecting voltage between a drain terminal and a source terminal of the synchronous rectifier reaches a second reference voltage, the driving voltage applied at a gate terminal of the synchronous rectifier is decreased to regulate the drain-source detecting voltage to a first reference voltage. The first reference voltage is lower than the second reference voltage. And when the drain-source detecting voltage reaches an off reference voltage, the synchronous rectifier is turned off.
