Abstract
A switched-mode power supply includes: a Buck converter; and a control circuit for the Buck converter, which includes: a switching unit configured to generate a switching control signal based on a feedback voltage of the Buck converter and a compensation ramp voltage; a transconductance amplifier, where a first input terminal and a second input terminal of the transconductance amplifier are configured to receive a reference voltage and the feedback voltage, respectively; a switch coupled between an output terminal of the transconductance amplifier and a first node, where the switching unit is coupled between the first node and the Buck converter; a compensation control circuit coupled to a control terminal of the switch and configured to open or close the switch based on a first signal representative of a current flowing through an inductor of the Buck converter; and a ramp signal generator configured to generate the compensation ramp voltage.
