Claim 13:
14. A method comprising:
generating a ramp for determining a phase shift between a first phase and a second phase of a power converter;
generating a plurality of set signals, wherein two adjacent set signals are used to determine a turn-on instant of a high-side switch of the first phase and a turn-on instant of a high-side switch of the second phase of the power converter, respectively, wherein generating the plurality of set signals comprises converting the ramp into a first current, converting a difference between an error signal and a feedback signal into a second current, feeding a combination of the first current and the second current into a resistor to generate a triangular waveform and comparing the triangular waveform with a predetermined reference to generate the plurality of set signals;
generating a plurality of first reset signals for determining turn-off instants of the high-side switch of the first phase, wherein the plurality of first reset signals is generated by an on-timer comprising a current source and a capacitor connected in series between an input of the power converter and ground, and wherein a current flowing through the current source is proportional to an input voltage of the power converter, and wherein the input of the power converter is directly connected to high-side switches of the power converter; and
generating a plurality of second reset signals for determining turn-off instants of the high-side switch of the second phase.
