Claim 0:
1. An apparatus, comprising:
a voltage regulator circuit configured to generate a particular voltage level on a regulated power supply node using a first regulation mode;
a detection circuit configured to detect a regulation event using a voltage level of the regulated power supply node; and
a control circuit configured to:
in response to a detection of the regulation event, change an operating mode of the voltage regulator circuit from the first regulation mode to a second regulation mode; and,
in response to a detection of an end condition for the second regulation mode, change the operating mode from the second regulation mode to the first regulation mode;
wherein one of the first and second regulation modes includes a valley-current regulation mode, and wherein another one of the first and second regulation modes includes a peak-current regulation mode.
