Abstract
A control circuit for a power converter employing a depletion mode switch and a method of operating the same. In one embodiment, the control circuit includes a controller configured to control the depletion mode switch by providing a drive signal to a control terminal thereof as a function of a characteristic of the power converter. The control circuit also includes a protection circuit configured to induce an application of a drive signal having a non-zero value to the control terminal to substantially disable the depletion mode switch in response to a transient condition of the power converter.
