Abstract

A power conversion circuit has multiple phases wherein each of the phases has an inductor coupled to a power switch circuit and is coupled to an output node. A power conversion controller controls the switching of one or more of the phases to yield a regulated voltage on the output node. The controller uses a variable inductor current limit for one or more designated phases, and temporarily increases the variable inductor current limit during a transient condition. Other embodiments are also described and claimed.
