Patent ID: 8917034

Claim:
An apparatus comprising: an amplifier including an input terminal and an output terminal configured to provide an output voltage; a sense transistor including a sense gate coupled to the output terminal of the amplifier and configured to provide a sense voltage using a first input voltage; a sink transistor including a sink gate coupled to the output terminal of the amplifier, the sink transistor coupled to an electronic component and configured to provide a sink voltage using a second input voltage; a switched feedback circuit configured to selectively precondition the sense and sink gates using the output voltage of the amplifier by selectively coupling the sense voltage and the sink voltage to the input terminal of the amplifier based on the second input voltage, wherein the switched feedback circuit includes: a comparator configured to generate an output and to be coupled to the sink transistor and the electronic component; and a switch coupled to the comparator and the sense and sink transistors, the switch configured to selectively couple at least one of the sense and sink transistor to provide at least a respective one of the sense and sink voltage to the input terminal of the amplifier based, at least in part, on the output of the comparator; wherein the second input voltage is configured to be selectively enabled, the second input voltage configured to vary from an initial voltage to a final voltage upon the second input voltage being enabled; and wherein the switched feedback circuit is configured to selectively couple the sense voltage to the input terminal of the amplifier to limit a current overshoot in the electronic component.
