Abstract
Embodiments disclosed herein describe the use of two inductors in a non-isolated power converter. The power converter receives power from a non-regulated power source, and converts the received power to regulated output signals. Each inductor in the power converter receives power provided from the non-regulated power source via a switch controlled by a controller, and provides a regulated output to a power converter load. A first regulated output provided by a first inductor can be representative of a second regulated output provided by a second inductor. In addition, a voltage feedback signal can be provided for use by the controller based on the first regulated output and/or the second regulated output.
