I have always used Linear Tech's switchers. I think there may be some
sort of design tool available, but I've never really looked into it.
LTSPICE has all of their parts, of course. I've never even had to look
past their datasheets for tips. They're well written, give example part
numbers where important (for example, tantalum capacitors, inductors,
etc.), and lots of example circuits as well as well as board layout
recommendations. Built a few buck, boost, and buck-boost power supplies
on my own single sided PCBs using their high-frequency switchers. I'm
surprised nothing has yet to go wrong with those, even after abuse. So
all in all, pretty brainless as long as you read the datasheet.

Only reason I'm not hesitant to recommend them is that they're not
stingy with their free samples, have PLENTY of DIP/TO-220 style
packages, and so many different types to choose from.
