Likely yes, but you’d have to try it yourself since I don’t have this plugin.

Retrode 2 N64/GBx plug-in needs a 3.3V to 5V voltage converter, would this work?

There are many ways to do this depending on current/ripple/type of load. Describe your application (in 10 words or less)?

hello, how can I change 5v DC to 3.3v DC?

I would like to purchase two of these converters, are you producing them yet? I cannot seem to find them in the store. Thank you!

I don’t think this can be done – for your spec you’ll need 10A input current and therefore losses will be excessive.

We need 0.5VDC- 5VDC (500 mas) converter . Can you supply?

Oh, my mistake! My screen is 1024×768 and I’m using firefox so the words ran together and I didn’t see the “Bare PCB” part.

Thanks for clearing that up.

I don’t think I’ll need a PCB as I can just add a little section on the one I’m designing for this. There’s some extra space anyway on the thing anyway.

Sparkfun’s converter is nice but I really need the switch on and off capability. Thanks for the help.

Where do you see it? I only see bare PCB of this converter listed at the store and it is indeed available. I discontinued this converter and designed a better one -> http://www.circuitsathome.com/dc-dc/5v-buck-converter-for-battery-operated-projects ; I’m yet to start producing it but if you’re comfortable soldering 3mmx3mm QFNs, I can send you a blank PCB of it – contact me off-list at mazurov at circuitsathome.com . Also, Sparkfun sells a boost converter (my design also) -> http://www.sparkfun.com/products/10255 which can be used as 3.3V to 5V booster.

Oleg, I’m assuming from the fact that it can be selected in the store and checked out and stuff that this converter is once again for sale.

Please correct me if I’m wrong as I’d like to be absolutely sure.

Other than that about how long would the shipping time be? It would be shipped to Pennsylvania.

If you’re not selling them right now or if it will take too long to get here I guess I’ll just order the individual parts and build it myself, and incorporate those on the PCB for the project I’m working on.
