Abstract

A method of charging a battery comprising receiving a first input voltage and a first input current at the input of a switching regulator; generating a first output current from the switching regulator to the battery, wherein the first output current to the battery is greater than the first input current; and reducing the first output current as the first output voltage on the battery increases and a corresponding battery charger.

Description

technical field [0001] The present invention relates to switching battery chargers, and more particularly to switching battery charging systems and methods. Background technique [0002] Batteries have long been used as a power source for mobile electronic devices. Batteries provide energy in the form of current and voltage that allow circuits to operate. However, the amount of energy stored in the battery is limited, and the battery loses power when the electronic device is in use. When the battery's energy supply is depleted, the battery's voltage will begin to drop from its rated voltage, and electronic devices that rely on the battery for power will no longer function properly. These thresholds will be different for different types of electronic devices. [0003] Many types of batteries are designed for a single use. These batteries are discarded after being depleted of charge. However, some batteries are designed to be rechargeable. Rechargeable batteries typicall...
