Abstract: An illustrative example embodiment of a method is for controlling a switch. The switch is used to charge a capacitor that provides an output voltage. The switch has an inductor on an input side between a power source and the switch. The method includes: initiating a switching cycle including turning on the switch, sensing a voltage representing current through the inductor, using a reference voltage as a basis for turning off the switch during the switching cycle when the sensed voltage exceeds the reference voltage, and setting an initial value of the reference voltage at a beginning of the switching cycle based on at least one feature of an activation of the switch during at least one previous switching cycle.

Abstract: A gate-driver device for operating a field-effect-transistor (FET) includes a pull-down-block and a pull-up-block resistant to or protected from short circuits of the gate drive signal output by the device. The pull-down-block is operable to drive a gate of a FET to a low-voltage. The pull-up-block includes a resistive-pull-up operable to an ON-state and an OFF-state to switchably couple the gate to the high-voltage via an upper-resistive-element, and a current-pull-up arranged in parallel with the resistive-pull-up. The current-pull-up is operable to an ON-state and an OFF-state to control a current-source applied to the gate. When the pull-up-block drives the gate to the high-voltage, the resistive-pull-up and the current-pull-up operates from the OFF-state to the ON-state. A turn-on-interval after the resistive-pull-up operates from the OFF-state to the ON-state the resistive-pull-up operates to the OFF-state while the current-pull-up is maintained in the ON-state. Optionally, the pull-down-block may be similarly configured.
