Abstract
An apparatus includes a ramp generator configured to produce a set signal for determining a phase shift between a first phase and a second phase of a power converter, a first phase on-timer configured to produce a first reset signal for determining a turn-on time of a high-side switch of the first phase of the power converter, a second phase on-timer configured to produce a second reset signal for determining a turn-on time of a high-side switch of the second phase of the power converter, and a control logic block configured to generate gate drive signals for the first phase and the second phase of the power converter based on the set signal, the first reset signal and the second reset signal.
