Abstract
In one embodiment, a power supply controller may be formed including configuring the power supply controller to use an error signal and a ramp signal to control a duty cycle of a switching control signal that is configured to control first and second switches to charge a battery, and configuring the power supply controller to selectively offset a dc value of the ramp signal responsively to detecting the adapter current is greater than a first value wherein offsetting the dc value of the ramp signal changes the duty cycle of the switching control signal to supply current from the battery to a load.
