Multiphase power converter with CLC resonant circuit. One example is a method of operation a power converter, the method including: charging, during a first on-time, a first output inductor by way of a first switching-tank circuit defining a first switch node coupled to a first lead of a resonant inductor; creating, during the first on-time, a first current flow into the first switching-tank circuit through the resonant inductor; and then charging, during a second on-time, a second output inductor by way of a second switching-tank circuit defining a second switch node coupled to a second lead of the resonant inductor; and creating, during the second on-time, a second current flow into the second switching-tank circuit through the resonant inductor.
