Abstract:
In one embodiment, the present invention includes a circuit having a voltage estimation circuit to receive a first voltage and generate an estimation of an output voltage of a power conversion circuit based on the first voltage. The first voltage is from a circuit node between a first terminal of a switch and a first terminal of an inductor. The circuit further comprises a current estimation circuit to receive a first current and generate an estimation of an output current of the power conversion circuit based on the first current. The first current is a current through the switch. The circuit further includes a pulse width modulation circuit to produce a pulse width modulated signal based on the estimation of an output voltage and the estimation of an output current.
