Abstract
Several circuits and methods for driver control of a switching circuit are disclosed. In an embodiment, a circuit for driver control of a switching circuit includes a driver circuit and a control circuit. The driver circuit is capable of being coupled to the switching circuit. The switching circuit includes a first switch and a second switch. The driver circuit is configured to control a conductive state of the switching circuit by facilitating an alternate state change of the first switch and the second switch. The control circuit is coupled to the driver circuit and is configured to detect a noise signal during a state change of the first switch. The control circuit is further configured to control the driver circuit to thereby slow down the state change of the first switch.
