    摘要： A switch control circuit includes a power switch, a first protection unit, and a second protection unit. The power switch has a first terminal coupled to a first voltage terminal for receiving a first voltage, a second terminal coupled to a second voltage terminal for receiving a second voltage, and a control terminal receives a control voltage. In a first mode, the control voltage is greater than the first voltage. In a second mode, when a voltage of the second voltage terminal is smaller than a first reference voltage, the first protection unit pulls down the control voltage to reduce a current flowing through the power switch. When the voltage of the second voltage terminal is smaller than the second reference voltage, the second protection unit pulls down the control voltage to a ground voltage.

    摘要： Circuitry for soft shutdown of a power switch and a power converters that includes circuitry for soft shutdown are described. In one aspect, circuitry for soft shutdown of a power switch includes a sense input to be coupled to a power switch receive a signal representative of current passing through the power switch, a comparator to compare the signal with an overcurrent threshold indicative of an overcurrent condition of the power switch and to output a triggering signal in response to the comparison indicating the overcurrent condition, and a gating transistor to be coupled to a control terminal of the power switch, the gating transistor configured to divert a portion of a drive signal away from the control terminal of the power switch in response to the triggering signal.
