Abstract
The present embodiments allow multiphase buck controllers to be able to detect Power-on-Reset (POR) automatically and subsequently reboot the system and reconfigure the system as a single or multi-rail system. Some embodiments use an onboard bus that can communicate between controllers. In these and other embodiments, the system is able to recover automatically from a power failure afflicting any or all of the controllers. Embodiments are applicable to flexible plug-and-play modular digital buck regulation applications.
