Abstract:
The present invention discloses a switching regulator with transient control function, and a control circuit and a method for controlling the switching regulator. The switching regulator with transient control function includes: a power conversion circuit for receiving an input voltage and converting the input voltage to an output voltage; a feedback circuit for detecting the output voltage and generating a feedback signal representing the output voltage; an output capacitor coupled to an output terminal of the power conversion circuit; and a control circuit for receiving the feedback signal and generating a control signal to control the conversion operation by the power conversion circuit accordingly, wherein the control circuit includes a voltage balancing circuit which discharges the output capacitor when the output voltage is higher than a first predetermined threshold, and charges the output capacitor when the output voltage is lower than a second predetermined threshold.
