Abstract
The present embodiments are directed to methods and apparatuses for operating a battery charger in computing systems having certain system load requirements, battery configurations and external device power supply support. According to some aspects, the present embodiments provide methods and apparatuses for providing a reverse boost mode of operation when the battery charger is providing system power from a battery, such as when an adapter is not connected. The reverse boost mode of operation according to embodiments provides a regulated output voltage, thereby allowing a load such as a CPU to operate at maximum performance, even when the battery has discharged below a threshold discharge level.
