Hi,
Well one thing I've never really understood is Buck Converters, especially multi-phase Buck Converters.
I found this which really helped:

On that thread, there was this diagram:

That has tought me a bit. The thread also linked to this:
**broken link removed**
But that page doesn't really help because it starts off jumping into
"In our switched inductor example we used the rule of thumb of designing L to get a peak-to-peak ripple current of 10% of the full load ......." which is jumping the gun for me.
Oh and I also found this:
http://en.wikipedia.org/wiki/Buck_converter
Which seemed to help a bit.
Anyway, I was wondering if some of you can help me learn about inductors and Buck Converters.
Also how are they driven ? Can you show me a simple analogue driver for one ? Not some fancy IC which does it all for you, as that isn't really useful for learning about them.
Also, on the diagram above, how could that be driven ? I simulated it in Livewire but didn't get very far.
Finally, how do you do simple calculations for the values of L and C ? The webpage above has some formulas but they are way over my head.
Thank you,
-Andrew.
