Abstract

A method includes generating a first ramp signal for controlling a first portion of a converter, generating a second ramp signal for controlling a second portion of the converter, controlling a state of a first switch of the first portion through comparing the first ramp signal to a control signal and a state of a first switch of the second portion through comparing the second ramp signal to the control signal and determining a switching cycle of the converter through comparing a current flowing through an inductor of the converter to a threshold.
