ABSTRACT:
Various apparatuses, methods and systems for a front end protection circuit with a dynamic charge pump system are disclosed herein. For example, some embodiments provide an apparatus such as a voltage regulator, a current regulator, a driver circuit or a switch protection circuit. The apparatus includes an output switch, a switch controller and a voltage threshold detector. The apparatus operates in a reduced power mode when the threshold detector detects a feedback level passing a threshold. In some particular embodiments, the switch controller includes a charge pump and an oscillator that run at lower speeds to reduce power usage when the feedback level passes the threshold. In various embodiments, the feedback level is a voltage level at the output switch control input, the output voltage from the output switch, or the output current from the output switch.
