Abstract: Circuits and methods that control a rate of change of a drain voltage as a function of time in a transistor are disclosed. In one aspect, the circuit includes a transistor having a gate terminal that controls operation of the transistor, and a control circuit coupled to the gate terminal and arranged to change a voltage at the gate terminal at a first rate of voltage with respect to time from a first voltage to a first intermediate voltage, and further arranged to change the voltage at the gate terminal at a second rate of voltage with respect to time from the first intermediate voltage to a second intermediate voltage, where the first rate is different than the second rate.

Abstract: A power converting system produces an input signal regulated with respect to an input signal. The power converting system has a first inductive element having a first node coupled to an input node, and a second inductive element having a first node coupled to an output node. A first switching element is coupled to a second node of the first inductive element. A first capacitive element is coupled between the second node of the first inductive element and of the second inductive element. A control circuit sets a duty cycle of the first switching element to a first value for providing the output signal of a first polarity responsive to the input signal of the first polarity, and to set the duty cycle of the first switching element to a second value for providing the output signal of a second polarity responsive to the input signal of the first polarity.
