1. An apparatus comprising:
a first power converter circuit configured to generate a particular voltage level on a converter power supply node based on a voltage level of an input power supply node;
a host power converter circuit coupled to a regulated power supply node via a first inductor, wherein the host power converter circuit is configured to:
generate an internal demand current and an external demand current using a voltage level of the regulated power supply node and a reference voltage; and
source a first current to the regulated power supply node using a voltage level of the converter power supply node; and
a first follower power converter circuit coupled to the regulated power supply node via a second inductor, wherein the first follower power converter circuit is configured to source a second current to the regulated power supply node using the voltage level of the converter power supply node.
