1. An apparatus, comprising:
a first phase circuit included on a first integrated circuit, wherein the first phase circuit is configured to activate, using a first phase clock signal, a first driver circuit coupled to a regulated power supply node via a first inductor, wherein the first driver circuit is included on the first integrated circuit, and wherein the first driver circuit is configured to source a first current to the regulated power supply node during a first on-time period; and
a second phase circuit included on the first integrated circuit, wherein the second phase circuit is configured to activate, using a second phase clock signal, a second driver circuit coupled to the regulated power supply node via a second inductor, wherein the second driver circuit is configured to source a second current to the regulated power supply node during a second on-time period.
