@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.
