Can I build an AC/DC SMPS in 1 month?
(1/5) > >>
KEIN NEIN:
I need to finish to projecs in one month:

One that has a transistor in it
And one that uses arduino

I was planning to build an SMPS + DC load and osciloscope but having seen I don't have a lot of time, should I continue with the SMPS or should I just build the load (which also has a transistor)

Can you help me select the right parts?

Thanks in advance

Simplest SMPS with built-in protection ...
To build it follow instructions in design sheet
http://www.datasheetcatalog.com/datasheets_pdf/R/D/6/RD6.shtml
Dont forget transfomer GAP size or AL(nH/turns2) found in sheet
parts available on Mouser, Digikey ...

I see, thanks

But what if I wanted to make a higher power SMPS, could I just use higher rating parts?

Or would I have to opt for a difference topology
KEIN NEIN:
Is it worth it to do something like a quasi reasonant psu just for efficiency reasons?
