Patent ID: 8084884

Claim:
A power control architecture, comprising: a plurality of multi-phase buck converter modules, each module electrically connected to a load, each of the multi-phase buck converter modules being adapted to generate a load current monitor signal for its respective load; a signal conditioning circuit electrically connected to each of the multi-phase buck converter modules, the signal conditioning circuit adapted to receive the load current monitor signals from each multi-phase buck converter module and to generate a conditioned signal therefrom; a controller adapted to receive the conditioned signal from the signal conditioning circuit and to generate control information based upon the conditioned signal; and a power conversion circuit adapted to receive the control information from the controller and to issue a variable driver voltage signal to each of the multi-phase buck converter modules to reduce conduction losses associated with each multi-phase buck converter module supplying power to its respective load wherein the signal conditioning circuit includes a signal processing apparatus for integrating and averaging of the load current monitor signals and for issuing an output signal used to generate the conditioned signal; and wherein the signal conditioning circuit further includes a multiplexer that receives the output signal from the signal processing apparatus, multiplexes the output signal with a power signal upon receipt of a control signal, and generates the conditioned signal.
