Abstract
A method includes simultaneously driving a load via first and second magnetically coupled regulator phases for a first duration, uncoupling one of the phases from the load after the first duration, and, after uncoupling the one phase from the load, allowing a current through the one phase to decay. For example, such a method allows energy stored in the uncoupled phase to be recaptured to the output transient response of a power supply.
