1. An integrated circuit comprising:

  • a switching circuit to provide a switching signal to the control terminal of a switching transistor, the switching transistor having a first terminal to receive power from a power source, a second terminal to provide power to a battery through a filter, and a control terminal;

    a current control circuit to receive an input signal corresponding to a sensed current and to provide a control signal to the switching circuit to control the sensed current,wherein an output current into the battery from the second terminal of the switching transistor is greater than an input current into the first terminal of the switching transistor from the power source,and wherein the output current is reduced, in a current control mode, as a voltage on the battery increases.
