View Full Version : 5A+ Switching Voltage Regulators?

I'm in need of some switching voltage regulators that can support 5A or more of current. I can't find anything over 1A (like the ones here on Trossen's site). Is such a thing made or do I need to wire 5 of the 1A voltage regulators in parallel? I'd like to have an adjustable regulator, but if not I'll need one that can take 12V Vin and 6V Vout.

Thanks,
James

Sweet Thanks! I was actually looking for something with the "external components" included in the package, so I don't have to solder together a circuit.

Yeah, that's kind of the holy grail for these things, which is why the Dimension Engineering parts are so nice...

So you need a DC-DC 12v DC in, 6v DC out @ 5A?

I generally turn to Powerstream for stuff like that...

That's 12vDC to 6vDC @ 11A continuous

Wow! Powerstream has some really cool stuff. This is the first time I heard about them.

I want one of these:

If you didn't recommend this place, I'd think it was a scam site. It doesn't look like they've changed the theme since 2001.

I don't know how strong a recommendation, but they've delivered product to me before over the years, for about $750ish total.

They're very Trossen-like in that they're really just a reseller of Chinese imports and creative small manufacturers.

I own one of these, and would have recommended it, but noticed it was out of production. Ashame, it's done a good job off and on for several years.

I've used one of these before, but I believe it came from a place called "group mobile" or something like that... It's actually made by a company that is monetizing a discovery made at my ol' alma mater. I used it on a McKinley summit attempt for charging radio batteries and satellite phone batteries. They run about 8hrs on that little cell, but they have other options too. I believe their website is http://www.ultracellpower.com

Powerstream has a 4A continuous 120AC->12DC switching inverter in their "garage sale" for like $12. I just paid $35 for the exact same unit somewhere else last month. Works great, pulls 5A without heating up too much, and is super clean, almost lab-supply clean. It's a steal at $12.
