1. An integrated circuit comprising:
a data circuit that processes data traffic;
a switch mode voltage regulator to provide a power supply to the data circuit, wherein the voltage regulator includes a plurality of phases; and
a control circuit coupled to the voltage regulator to:
determine a bandwidth of the data traffic over a sampling window; and
control a number of the phases that are active based on the determined bandwidth, wherein the control circuit is to determine the bandwidth of the data traffic based on an ingress counter that corresponds to incoming data to the data circuit and an egress counter that corresponds to outgoing data from the data circuit.
