Abstract
A constant ON-time converter is disclosed. The constant ON-time converter comprises a feedback circuit, a slope compensation circuit and a buffer circuit. The feedback signal comprises an output configured to provide a feedback signal indicating an output voltage of the constant ON-time converter. The slope compensation circuit comprises an output configured to provide a slope compensation signal. The buffer circuit is coupled between the output of the feedback circuit and the output of the slope compensation circuit to avoid the feedback signal and the output voltage of the constant ON-time converter is influenced by the slope compensation signal.
