Tool/software: WEBENCH® Design Tools
The "classic" Webench keeps on badgering about moving to the "improved" HTML5 webench. Yes, the new version does have a cleaner look and I suppose it's easier to use for someone who doesn't want to get into feedback loop design. Unfortunately there are key pieces of functionality missing that does exist in the flash version. Tweaking feedback loop and thermal simulation are missing completely. For custom parts you have limited parameters you can define for inductors and capacitors.
The HTML5 Webench hasn't changed much since I first tried the beta. Is the missing functionality being developed or the HTML5 version will remain as Webench "lite"? Is the "classic" tool going to be discontinued in near future? Especially tweaking the feedback loop is an enormously useful feature that's almost trivialised SMPS design for me, and Texas SMPS controllers have been a staple of my designs for many years now..
