Abstract
A circuit arrangement is disclosed for controlling the switching of a field effect transistor (FET). A current controlled amplifier may be configured to amplify a current in a current sense device to generate an amplified current, wherein the current in the current sense device indicates a current through the FET. A comparator may be coupled to the current sense amplifier to compare a voltage corresponding to the amplified current with a voltage reference and to generate a comparator output based on the comparison, wherein the comparator output controls whether the FET is on or off.
