Abstract
A power system having a power converter with an adaptive controller. In one embodiment, a power converter coupled to a load includes a power switch configured to conduct for a duty cycle to provide an output characteristic at an output thereof. The power converter also includes a power converter controller configured to receive a signal from the load indicating a system operational state of the load and enable a power converter topological state as a function of the signal.
Claims20
A power converter coupled to a load, comprising:
- a power switch configured to conduct for a duty cycle to provide an output characteristic at an output thereof;
- and
- a power converter controller configured to receive a signal from said load indicating a system operational state of said load and control an internal operating characteristic of said power converter as a function of said signal.
A power system, comprising:
- a power system controller configured to provide a signal characterizing a power requirement of a processor system;
- and
- a power converter coupled to said processor system, comprising:
- a power switch configured to conduct for a duty cycle to provide an output characteristic at an output thereof, and
- a power converter controller configured to receive a signal from said power system controller to control an internal operating characteristic of said power converter as a function of said signal.
A power system, comprising:
- a power system controller configured to enable operation of components of a processor system to establish a state of power drain thereof, said power system controller configured to provide a signal to identify operation of said processor system in said state of power drain;
- and
- a power converter, coupled to said processor system, comprising a power converter controller configured to receive said signal from said power system controller, to sense a power level of said state of power drain in response to said signal, and to control an internal operating characteristic of said power converter as a function of said power level.
A method of operating a power system, comprising:
- enabling operation of components of a processor system to establish a state of power drain thereof;
- providing a signal to identify operation of said processor system in said state of power drain;
- sensing a power level of said state of power drain in response to said signal;
- and
- controlling an internal operating characteristic of a power converter as a function of said power level.
