Abstract
A power supply is disclosed for use in battery powered electronic devices. The power supply includes a power source which supplies power to the electronic device itself as well as to battery charging circuitry integral to the power supply. The battery charging circuitry monitors an output current, or other parameter, of the power source output. Feedback circuitry regulates the output of the battery charging circuitry so that output current, or other parameter of the power source output, is kept within predetermined limits.
