Effective Optimization of Power Management Architectures through Four standard “Interfaces for the Distribution of Power”
October 07, 2014
In the promising market of the Internet of Things (IoT), System-on-Chips (SoCs) are facing exponential design complexity challenges and ultra lower power consumption requirements. The architectural definition, component selection and integration of power management play a major role in the quest of device minimization and battery lifetime maximization.
In order to reach the best Return on Investment (RoI) and Time-to-Market (TTM), Dolphin Integration launch the disruptive approach of a DELTA Reusable Power Kit Library (RPKL) for building power management architectures with reusable regulation components. The concept of Figure of Merit (FoM) is introduced for the RPKL approach to select the optimal power management solutions per application requirements with the best trade-off among diverse performance criteria, be it power consumption, silicon area or Bill-of-Material.
The standardization of four Interfaces for the Distribution of Power (IDP) is a sine qua non condition of the RPKL approach, as it leads to reusable regulators and allows a smooth combination with in-house or third party regulators. The selection of the four voltage levels and their range of accuracy is explained and the benefits are provided.
Finally, the seven rules of the DELTA standard are shared and, as long as any regulator is designed per these rules, it can partake in the optimal power management solutions with the best management of integration risks through EDA simulation and verification.
