Abstract
Exemplary embodiments may include a method of applying a charging pulse to an output capacitor, detecting satisfaction of a charging threshold, ending the charging pulse in response to the detecting the satisfaction of the charging threshold, and discharging the sampling capacitor in response to the detecting the satisfaction of the charging threshold. In some embodiments, once a sampling capacitor voltage drops below a discharging threshold, a charging pulse is applied. Exemplary embodiments may also include an apparatus with a controller coupled to an input node, a timer coupled to the controller, an inductive charger coupled to the controller, to an input node, and to an output node, and a sensor coupled to the controller and the output node. Exemplary embodiments may further include an apparatus where a sensor with a sampling capacitor has a first terminal coupled to the output node and a second terminal coupled to the controller and the inductive charger.
