    Abstract: Aspects of the present disclosure provide for a method. In at least some examples, the method includes controlling gate terminals of one or more transistors of a charger to operate the charger in a buck-boost mode of operation to generate a system voltage based on a bus voltage by performing power conversion through switching, determining that the bus voltage is greater in value than a voltage of a battery coupled to the charger, and controlling the gate terminals of the one or more transistors of the charger to operate the charger in a pass-through mode of operation to generate the system voltage based on the bus voltage without performing power conversion.

    Abstract: A multiphase DC-DC converter includes a first phase circuit including a higher inductance inductor and a second phase circuit including a lower inductance inductor. An output of the inductors are tied together providing a Vout. A phase manager and current sharing (PMCS) block receives a feedback signal from a feedback network coupled between Vout and the PMCS block that receives current feedback from phase circuits. The PMCS block generates driver control signals at a first time when a load is requesting a lower load current for controlling the phase circuits to operate with a first current sharing ratio to provide the lower load current, and at a second time when the load is requesting a higher load current controls the phase circuits to operate at a second current sharing ratio that is different from the first current sharing ratio having a higher average second phase circuit current.
