5v Switching regulator instead of 7805

[Futureman]

Has anyone tried one of these?

With my new sequencer using VFD's and plenty of backlighting, my 5v regulator gets rather hot, and will need a heatsink the size of a small country.

I was thinking of something like this instead.

Any ideas?

They are using a LM2575-5. I assume you can quite easily make it yourself. I haven't tried one myself.

But switching psu are much more efficient then liniar ones. So if you are not using a MB wich has analog audio, its ok to use a switching psu.

interesting.

I have had my eye one these for a while: http://www.dimensionengineering.com/DE-SW050.htm but that definitely trumps it on price. Would be nice for my MB808 which has to burn off 10V on the 7805
