ABSTRACT:
A multi-phase DC-DC converter incorporates auxiliary resistor networks to feed back to the converter's supervisory controller voltages representative of secondary sensed currents associated with primary currents sensed relative to the common nodes of the respective phases, and derived from the output nodes for each phase. The auxiliary resistor network-coupling of these secondary sensed currents enables the controller to more completely take into account the influence of the currents of each channel on every other channel, whereby phase-balanced control of all converter channels is achieved, irrespective of symmetry of the integrated circuit layout of the different phases of the converter.
