Abstract
A multi-phase buck converter comprises a first comparator, a second comparator and a counter. The first comparator has a first node connected to a first voltage reference and a second node. The second comparator has a first node connected to a second voltage reference and a second node. The second node of the second comparator and the second node of the first comparator are together connected to an input voltage from an active phase of the buck converter. The counter is configured to adjust a number of active phases of the buck converter based on the input voltage.
