Abstract
Embodiments of the present invention include techniques for charging a battery. In one embodiment, the present invention includes a method comprising determining if a maximum current output of a power source is above a threshold, configuring a regulator coupled to the power source, wherein the regulator is configured in a pass mode if the maximum current output is above the threshold, and wherein the regulator is configured in a regulation mode if the maximum current output is below the threshold, and generating pulses to a battery, wherein an output of the regulator is coupled to the battery when a pulse is being generated, and the output of the regulator is decoupled from the battery when a pulse is not being generated. In other embodiments, the techniques may be embodied in a circuit including a detection circuit and a switching regulator coupled to a battery through a pulse circuit.
