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.
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. :)
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.
@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.
