Patent ID: 8754619

Claim:
A multiphase power converter device comprising: a first cell operative to receive a first voltage signal and output a second voltage signal; and a second cell operative to receive the first voltage signal and output a second voltage signal, wherein the output of the first cell is connected in parallel with the output of the second cell such that an output (V out ) of the multiphase power converter includes the output of the first cell and the output of the second cell; wherein, the first cell includes: a power stage portion operative to receive the first voltage signal and output the second voltage signal; and a control portion operative to sense a current output by the power stage portion, receive a current set point value, process the current set point value to calculate a current set point associated with the first cell, and control the power stage portion such that the power stage portion outputs a current substantially equal to the current set point associated with the first cell; and wherein the second cell includes: a power stage portion operative to receive the first voltage signal and output the second voltage signal; and a control portion operative to receive a signal indicative of a current output by the power stage portion, receive the current set point value, process the current set point value as a function of the number of cells in the multiphase power converter to calculate a current set point associated with the second cell, and control the power stage portion such that the power stage portion outputs a current substantially similar to the current set point associated with the second cell.
