Assignee: APPLE INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G  H  Y | IPC G

Claim 17:
18. A system comprising:
a host circuit configured to send, via a first communication bus, a first telemetry request;
a memory circuit coupled to the host circuit; and
a first power group having a plurality of power circuits, wherein the plurality of power circuits includes at least one branch power circuit and at least one leaf power circuit coupled to the at least one branch power circuit in a hierarchical arrangement, wherein the at least one branch power circuit is configured to forward the first telemetry request to the at least one leaf power circuit, and wherein the at least one leaf power circuit includes:
a power converter circuit configured to generate a voltage on a regulated supply voltage node;
a sensor configured to generate telemetry data based on one or more measured operating parameters of the power converter circuit; and
an interface circuit configured to, responsive to receiving the first telemetry request, forward the telemetry data to the branch power circuit;

wherein the branch power circuit is configured to:
store the telemetry data; and
forward the telemetry data to the memory circuit; and

wherein the memory circuit is configured to store the telemetry data in a storage location within a particular range of addresses corresponding to the at least one leaf power circuit.
