"In the past, I have seen some self oscillating dc/dc converters. Will they be simpler as compare to this?"
yes hm, just look Bob Boschert's first switching mode power-supply some thirty years ego, that was the basis of his company "Boschert Computer products, he used 2 [two] transistors for a 25W off line power-supply....
I could not find the details about the controller TPS55010 indicated in the picture. Is it a new device, not launched yet?
Also I would be interested to learn about asymmetrical half-bridge flyback (I know flyback, synchronous buck but not "flybuck"). Unfortunately, I don't have access to IEEE and can't refer the paper mentioned in the "Reference".
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.
