    摘要: A rectifier including an autonomous type synchronous-rectification MOSFET is provided, which prevents chattering and through-current caused by a malfunction when a noise is applied. The rectifier includes: a rectification MOSFET for performing synchronous rectification; a determination circuit configured to input a voltage between a pair of main terminals of the rectification MOSFET, and to determine whether the rectification MOSFET is in on or off state on the basis of the inputted voltage; and a gate drive circuit configured such that a gate of the rectification MOSFET is turned on and off by a comparison signal from the determination circuit, and such that a time required to boost a gate voltage when the rectification MOSFET is turned on is longer than a time required to lower the gate voltage when the rectification MOSFET is turned off.

    摘要: A rectifier 107 includes a rectifying MOSFET 101 that performs synchronous rectification, a control circuit 106 that inputs a voltage across a pair of a positive-side main terminal TK and a negative-side main terminal TA of the rectifying MOSFET 101 to determine an ON or OFF state of the rectifying MOSFET 101 based on the inputted voltage, and a capacitor 104 that supplies power to the control circuit 106. The control circuit 106 includes a blocking circuit 105 that inputs the voltage across the pair of main terminals of the rectifying MOSFET 101, to block power supply to the control circuit 106 when the inputted voltage across the pair of main terminals is higher than or equal to a first voltage, and to unblock power supply to the control circuit 106 when the inputted voltage across the pair of main terminals is lower than the first voltage.
