Method and apparatus for regulating an output voltage of a power converter during a load transient

A controller for a power converter includes: an estimator configured to estimate or calculate a slew rate of an output voltage of the power converter or a slew rate of an error voltage which corresponds to a difference between the output voltage and a target voltage, during a load transient; and a m...

Beschreibung
Zusammenfassung:	A controller for a power converter includes: an estimator configured to estimate or calculate a slew rate of an output voltage of the power converter or a slew rate of an error voltage which corresponds to a difference between the output voltage and a target voltage, during a load transient; and a modulator configured to modify regulation of the output voltage based on the estimated or calculated slew rate. A corresponding voltage regulation method and an electronic system that includes the power converter are also described.
