1. An apparatus comprising:
a power circuit group having a plurality of power circuits, the plurality of power circuits being hierarchically arranged and including a branch power circuit and a leaf power circuit, wherein the 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 forward the telemetry data to the branch power circuit; and
wherein the branch power circuit is configured to forward the telemetry data to a memory circuit;
wherein the memory circuit is configured to store the telemetry data in a storage location within a particular range of addresses reserved for the leaf power circuit.
