摘要
A control circuit for controlling a power circuit having a power switch includes a control loop configured to generate a control signal for the power switch of the power circuit based on an error signal determined by comparing a sensed parameter of the power circuit and a reference signal, and a positive offset signal and a negative offset signal each configured to adjust the control signal. The control circuit is configured to detect a change in an output current of the power circuit and selectively apply only one of the offset signals based on the change in the output current to adjust the control signal thereby enhancing a dynamic response to the change in the output current. Additional example control circuits, example power supplies and/or power converters including a control circuit for controlling a power switch, and example control methods are also disclosed.
