摘要：
A method of operating a regulator controller IC for performing intermittent diode braking for controlling a multiple phase voltage regulator. The method includes receiving at least one signal for detecting repetitive load transients, determining a rate of the repetitive load transients, generating diode braking control signals, each for applying diode braking to a corresponding one of multiple phases for at least one load transient when the repetitive load transients are below a first rate, and controlling the diode braking control signals to drop application of diode braking of at least one phase for at least one load transient when the repetitive load transients are at least the first rate. The method may include rotating the application of diode braking among the phases during successive applications of diode braking. The method may include dropping an increased number of phases for diode braking as the rate of repetitive load transients is increased.
