Hello everybody, I've just signed in...

Anybody knows the shipping cost to Brazil?

Regards,

Adriano

Hello guys
What do you think about using that PS for powering WaveIO XMOS based converter from Lucian? Its 5V but 500mA power hungry! Would it be big heat problem and I should search other solutions?

Salas · 18th August 2012, 08:03 AM

3.5W total dissipation for 10V in 5V out for 700mA reg's CCS setting & 500mA load.

Could you please explain it to me in more easier words sir?

I have very little experience in electronics and dont know if its worth and I would have to buy BIG heatsink for proper work? What temperature should I expect from such PS without box? Im searching best solution and so far tried only 12V, 7,4 Ah accumulator through simple regulator but its annoying checking it day after day

Zib,
start with something simpler and increase your ambitions as your learning proceeds.

Get a 9V 1A transformer, get one 5C/W side sink common to the reg's 2 power semis & TO-220 silicone pads. Set it at 700mA, and expect ~25C above ambient temperature on the sink. More in the builds thread if you will decide to start with it, read the pdf guide in post #1 here first.
5C/W sink example.

Thank you Salas.
AndrewT its no problem, I have friends who could help me but already away or offline

I want to try that PS badly! If not with XMOS I could use it with other equipment

One more question - I assume Ill have to wait some time till next GB runs with sending kits. Can I buy for tests such regulator from Chinese seller and use it or its only similiar but much worse?:

Thank you

It looks decent, don't know about the first sink and your setting though, looks small. Not that cheap for just testing and then building another. Get one of those PCB thingies with LM2596 switchers for testing. Very cheap, tiny, no heat to speak about.
