Parameterization for power solutions

PMBus™ has done an excellent job of standardizing the way digital controlled power supplies communicate. However, this standardization has not included many of the traditional design requirements present in power supplies. A standardization proposal for the parameterization of power supply design requirements into a PMBus™ format is made. Benefits to the power supply design engineer and the host system are discussed. Examples are presented in the context of both isolated and non-isolated applications.
