Don't kill yourself with the MSOPs. The UCC series come in SOIC-8 packages which work just as well and have a thermal pad underneath.

I just had a thought, isn't it a bit odd how they provide UCCs in an MSOP8 package? UCCs are going to be driving something relatively large with their specifications, so space shouldn't be an issue should it? cheesey

Although I guess you can use them for a number of things not just driving large FETs...

It's too late EVR, I've already burned most of my fingerprints off working with these wink

BTW the SOIC8s I sampled have no powerpad on the bottom... which is why I'm guessing the dissipation is rated to 650mW max.

Perhaps I should crack my toaster oven out next time.. cheesey

I've never seen SOIC-8 packages with a powerpad either.

As a uttered perfboarder I curse all that: why couldn't they make DIP's with pad or just put them in TO220.. cheesey

IXDD414's are hard to get.. frown

Few times I tried, I never made a decent board for SMD except by hand with letraset, wich looks Very good while being huge pain to transfer on the board with just few small components..

If I needed I would probably make a board for these that way..

TO220 version anyone? tongue

Sink is ground so I can save 1 wire when I screw it on the Vregs' heatsink. Though these things have some benefits, I really think I wont use them in a SSTC because they are way to hard to make/replace.

Lots of manufacturers carry this package.
Micrel, for example . . .
