Abstract:
1. A circuit for controlling a switching regulator, the switching regulator comprising a switching controller and a regulator output terminal, the circuit comprising: an error amplifier comprising a first input terminal; a second input terminal; and an amplifier output terminal, said amplifier output terminal in electrical communication with said switching controller; a reference terminal in electrical communication with both the first input terminal of the error amplifier and a reference voltage; a feedback terminal in electrical communication with both the second input terminal of the error amplifier and the regulator output terminal; and an energy storage device comprising a first storage device terminal, the first storage device terminal in electrical communication with both the first input terminal of the error amplifier and the reference terminal, wherein the energy storage device provides a target voltage to the first input terminal of the error amplifier, wherein the target voltage has a first value corresponding to a voltage that is present at the regulator output terminal when the switching regulator is off, and wherein the target voltage has a second value corresponding to the reference voltage when the switching regulator is on.
