Abstract
In one embodiment the present invention includes a method of controlling a switching regulator based on a derived input current. In one embodiment, an output current of said switching regulator is detected and used to generate a first voltage or current signal corresponding to the output current. Additionally, a switching signal of said switching regulator is detected and used to generate a second voltage or current signal corresponding to the switching signal. The resulting signals may be combined to produce a voltage or current signal corresponding to an input current of said switching regulator. The switching signal may be modified based on the derived voltage or current signal and used to control the system.
