Abstract
A battery charging and power delivery system for a portable electronic device includes a first connection that connects the system to an AC/DC power adaptor. A second connection connects the system to the power bus of the portable electronic device. A third connection connects the system to a battery. A capacitor voltage divider circuit provides power to the system power bus through the second connection and provides power through the third connection. A controller provides control signals to the capacitor voltage divider and to the AC to DC power adaptor.
