Abstract
A multiphase power regulator includes a multiphase pulse width modulator, an output stage and an active transient response circuit. The output stage includes a high side transistor, a low side transistor and an inductor. The output stage is configured to supply power to a load responsive to signals generated by the multiphase pulse width modulator. The active transient response circuit is coupled between the output stage and the multiphase pulse width modulator and configured to detect the voltage level at the output stage and provide a signal to the multiphase pulse width modulator that is a function of the amplitude of the deviation of the detected voltage level from a target voltage.
