Abstract
A method includes converting a ramp voltage signal into a ramp current signal, a feedback signal into a feedback current signal, a reference signal into a reference current signal, and a control signal into a control current signal through a plurality of adjustable-gain units, and determining a turn-on of a high-side switch of a power converter through comparing a first control voltage and a second control voltage, wherein the first control voltage is generated based on a sum of the ramp current signal and the feedback current signal, and the second control voltage is generated based on a sum of the reference current signal and the control current signal.
