The present invention provides a nonlinear adaptive voltage positioning
DC-DC converter method and apparatus that enable improved voltage
transient response under changing current conditions for a load with
known current draw characteristics. The invention in some embodiments
provides that the nonlinear adaptive voltage positioning be adaptable or
configurable to a specific, known current load range that comprises less
than the full current range that may be provided by the DC-DC converter,
to optimize voltage transient response for a particular known load.
