Abstract: An output voltage is compared to a reference voltage, comparison signals are generated, and control signals and mode signals are generated in response thereto. The output voltage is generated in response to the control signals. A speed of the comparing is increased in response to the mode signals indicating that the output voltage is being increased. The speed is reduced in response to the mode signals indicating that the output voltage is being reduced. For increasing the speed, a path is enabled to conduct current. While the path is enabled, at least one switched voltage is connected to vary an amount of the current conducted through the path. The switched voltage is at least one of the reference voltage and the output voltage. For reducing the speed, the path is disabled against conducting current. While the path is disabled, the switched voltage is disconnected from varying the amount.

Abstract: A system includes a power supply source and a power control circuit coupled to the power supply source, in which the power control circuit includes a pass field-effect transistor (FET). The system also includes a short-to-ground protection circuit coupled to an output of the pass FET. The short-to-ground protection circuit includes a sense circuit configured to detect when a magnitude and a change rate of a voltage drop at the output of the pass FET is greater than respective thresholds. The short-to-ground protection circuit also includes a control node at the output of the sense circuit. The sense circuit is configured to induce a control current at the control node in response to the magnitude and the change rate of a voltage drop at the output of the pass FET being greater than respective thresholds. The control current is used to turn off the pass FET.
