At least one example describes mechanisms to improve performance of a multiphase voltage regulator. In at least one example, an integrated circuit is provided which includes control circuitry coupled to a first power stage and a second power stage. The first power stage and a second power stage are coupled to an output power supply rail, wherein the control circuitry generates a first pulse width modulated signal for the first power stage and a second pulse width modulated signal for the second power stage. In at least one example, the control circuitry aligns rise and fall times of the first pulse width modulated signal and the second pulse width modulated signal based on an undershoot condition being detected on the output power supply rail.
