Abstract
An apparatus and method for charging a battery includes a battery to be charged, a power delivery path configured for delivering power to the battery, and an integrated switching battery charger configured for charging a battery by delivering output power to the battery via the power delivery path based on input power from an input power source. The integrated switching battery charger includes an output voltage regulation loop and an input voltage regulation loop, both of which are configured to control the output current flowing out of the integrated switching battery charger to the battery. The input or output voltage regulation loops are further enhanced by adding a current source which is proportional to absolute temperature from the regulated voltage to the control voltage for the purpose of either regulating peak power from the source or to maximize energy storage in the battery as a function of temperature.
