Original Abstract Submitted
Embodiments herein describe a switchable redundant voltage regulator (referred to herein as a redundant phase) that can be attached to multiple different power domains. Instead of providing a redundant phase for every load or voltage domain in a computing system, the embodiments herein describe sharing redundant phases between voltage domains. Thus, if a primary phase serving any one of the phase fails, the switch can be controlled to connect the redundant phase to the corresponding voltage domain. In this manner, the redundant phase is a shared phase for a plurality of voltage domains.
