DC-to-DC converters capable of discontinuous conduction mode, and associated methods

Abstract:

A method for discontinuous conduction mode operation of a multi-phase DC-to-DC converter includes (a) forward biasing a first inductor being magnetically coupled to a second inductor, (b) reverse biasing the first inductor after forward biasing the first inductor, (c) while reverse biasing the first inductor and before magnitude of current through the first inductor falls to zero, forward biasing the second inductor.
