Abstract
An integrated circuit device includes: one or more switches of a Buck converter; and a control circuit for the Buck converter including: a comparator configured to generate a comparator output signal by comparing a feedback voltage of the Buck converter with a compensation ramp voltage; a pulse generator configured to generate, in response to a rising edge in the comparator output signal, a pulse signal for controlling the Buck converter; a transconductance amplifier configured to generate, at an output terminal of the transconductance amplifier, a current proportional to a difference between a reference voltage and the feedback voltage; a capacitor coupled between the output terminal of the transconductance amplifier and a reference voltage node; and a ramp signal generator configured to generate the compensation ramp voltage by adding a voltage at the output terminal of the transconductance amplifier and a ramp voltage generated by the ramp signal generator.
