Abstract
The present disclosure provides a power convertor circuit and a control circuit thereof. The power convertor circuit converts an input voltage signal to output an output voltage signal and includes a power stage circuit and a control circuit. The control circuit generates a first ripple signal according to a phase voltage signal outputted by the power stage circuit, generates a second ripple signal according to a DC signal generated by processing the first ripple signal, a reference voltage signal and a feedback signal related to the output voltage signal, and controls the power stage circuit to operate according to a preset off time when the second ripple signal continuously transcends the first ripple signal, to increase an inductor current. The control circuit calibrates the reference voltage signal by a DC offset calibration circuit, to eliminate an offset between the reference voltage signal and the feedback signal.
