looking at parts and datasheets to build a smps (switch mode power supply) and trying to figure out the networks that are rather complex from my point of view, I was expecting a list of 200 famous ICs like the lm317 or ne555 and when that seemed implausible, becuase there aren't that many iconic ones, I thought of insights into cmos design, which this hardly adresses and where 200 items would be a short list.
