Hi Stu,

On behalf of hard-bitten Ap. engineers everywhere, thank you!

You are ever so right about fast diodes, low ESR caps, low L Isense resistors and other stuff for switchers. These things just didn't exist 20 years ago. And we could have used them then but there wasn't a large enough driving force to make it worthwhile for the manufacturers.

This is either the best or worst of times, and I can't tell. While there are far more parts to choose from with "rich" feature sets, it's also very time consuming to source them. It can easily take half a day for one passive part. And things are more dangerous than they used to be, once dropping the 39 page Mouser catalog on your foot was nothing, the current 2000 page version can put you on crutches!

Regards, Rick
