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.
