There looks to be more BOM cost given to PSU functions than anything else, after the CPU. Of course the PSU earns its keep by getting max battery life from this CPU/display/memory but switchers are also a source of EMI, control of which adds more components.
I look forward to wide-range 200MHz converters with built-in L and C, sold in such huge qties that the cost is negligible, like the old 78xx series.
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.
