Simple buck converter schematics/circuits?

Jun 16, 2008 8 Replies

Can/would anyone/spomeone post a link to some simple buck converters that I could build at home (simple hand soldering, not surface mount)?



I've built simple 78/79/etc regulators in the past and want to compare this technology for efficency. Looking at dc to dc reduction only atm.



I have tried googling, but tend to get swamped in rrelevant stuff.



T.I.A.

Read this entire paper if you can, it's a good introduction:

Thanks. Very Handy and helpful. Should be able to play around a bit and build what I want.

Thank you. Helpful for simple chip stuff. Now to find a local source.

Unfortunately, never loads. Thanks anyway, will try a few more times.

Right clic, and select "save as", and get the file, then "open" it.

To vary the output voltage, does one have to change the zener diode?

Otherwise, what should be changed to turn this into a variable-output- voltage mini-LM317?

Thanks,
