Abstract:
1. A method of dynamic transient optimization in a voltage regulator, the method comprising: measuring a voltage error in the voltage regulator; setting an excursion signal at a first value when the voltage error exceeds a positive amplitude threshold and setting the excursion signal at a second value different than the first value when the voltage error exceeds a negative amplitude threshold, such that the excursion signal changes from the first value to the second value only when the voltage error changes from exceeding the positive amplitude threshold to exceeding the negative amplitude threshold and changes from the second value to the first value only when the voltage error changes from exceeding the negative threshold to exceeding the positive threshold, so as to define a window for which the excursion signal changes from one of the values to the other value so long as the voltage error changes from exceeding one of the amplitude thresholds to exceeding the other amplitude threshold; measuring a frequency of the excursion signal between changes in the excursion signal; and providing a corrective action if the frequency exceeds a frequency threshold, wherein one or both of the amplitude thresholds are programmable, wherein the frequency threshold is programmable.
