@Frank Eory: I had the same question. The article is unfortunately not detailed enough discern if PMIC functions are integrated. I think it makes more sense to leave those functions (driving and switching) seggregated from a board-level power management perspective.
True. But there're more to consider.
The more integrated your solution is, the less likely it would be flexible and cost- effective to your end users and this commodity market! You may argue that it is just a matter of time for the cost and flexibility to be of no issue, and you are right, it is just a matter of TIME for the chips to be a commodity. :)
Integration is the theme for everything now. When power management integrated the FETs, power stage engineers started to look for jobs; now it's the time for power engineers to think bigger than what we are doing right now.
I wonder whether it's just integration of a voltage regulator, or a complete power management system. If Intel has reached the point where they have integrated the essential PMIC functions, that is quite a big leap forward for them.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
