Abstract
The present invention relates to a circuit for emulating a current via a power inductor of a DC-to-DC converter. The circuit is able to generate a first signal and detect or emulate the constant component of the current by using a power inductor. The circuit is also able to generate a second signal or components of a second signal and emulate an alternating component of the current by using the power inductor. The circuit also is able to splice the first and second signal or the first signal and components of the second signal into a signal which at least partially emulates the current via the power inductor. The circuit able to generate a first signal may include a current sensing resistor connected to the power inductor and a first capacitor, and to a first input and output.
