Patent ID: 7576527

Claim:
A voltage converter comprising: an inductive load; a first resistive voltage divider that includes a first resistive element and a second resistive element where a first end of the first resistive element is coupled to a first end of the inductive load; a second resistive voltage divider that includes a third resistive element and a fourth resistive element where a first end of the third resistive element is coupled to a second end of the inductive load; an amplifier responsive to a first feedback voltage and to a first reference voltage, said first feedback voltage representative of a voltage at a second end of the first resistive element; a comparator responsive to an output voltage of the amplifier and a second feedback voltage at a second end of the third resistive element, said comparator to generate an output voltage applied to a control line of said voltage converter; and a voltage combiner to combine the output voltage of the amplifier with a second reference voltage, said voltage combiner to supply the combined voltage to the comparator.
