Abstract
In some examples, a controller is configured to control a power switch electrically connected in series with a winding. In some examples, the controller is also configured to control a pass switch electrically connected between an output node of the winding and a bus out node. In some examples, the controller includes a current source configured to selectively drive a charging current from an intermediate node between the power switch and the winding to a control terminal of the pass switch to turn on the pass switch.
