Patent ID: 8575910

Claim:
A system for controlling a voltage regulator having an output, the system comprising: means for generating an error value based on an output voltage developed at the output of the voltage regulator,. and a reference value; means for regulating steady-state behavior of the output voltage, according at least to a first control value derived from the error value; means for correcting the output voltage responsive to a transient deviation of the output voltage, according at least to a second control value derived from the error value; and means for adjusting a charge at the output of the voltage regulator during a present cycle and according at least to a third control value, responsive to the transient deviation of the output voltage, wherein the present cycle is subsequent to a preceding cycle during which the response of the voltage regulator to the transient deviation is corrected, and wherein the third control value is derived at least from: a value of the first control value during the present cycle; a value of the first control value during the preceding cycle; and a value of the second control value during the preceding cycle.
