Abstract
A system for distributing power between an external power supply, a battery, and a host device, the system comprising: an input terminal for coupling to the external power supply; a battery terminal for coupling to the battery; a first converter selectively coupled between the input terminal, the battery terminal, and a supply rail of the host device; and a second converter selectively coupled between the input terminal, the battery terminal, and the supply rail, the second converter being bidirectional; and control circuitry for controlling power distribution between the external power supply, the battery, and the supply rail via the first and second converters.
