For the basic principle read ArtOfElectronics. You can build a switcher yourself with PWM output of a PIC for example. But make sure your PIC never crashes :smile:

For good efficiency yet simple to use circuits look up Nationals SIMPLE SWITCHER series.

Buck -> Step-down converter
Boost -> Step-up converter

Buck : mainly PWM control
Boost : PWM,PFM.VFM control

Operation Mode : Continuos / Discontinuos Current Mode( according to inductor current)

Basic Topology -> TEXT BOOK ...

Thanks.

hi all.
I want to know theoretical and practical m@x response frequency of dc/dc converters, and which componets make the m@x response frequency limits?
thanks.

Re: Buck and boost

It is basic topology for dc-dc,i think you use google,you will find several huandreds imformation about it.

Ti,Maxim,Fairchild,national,All have applications about it.

Re: Buck and boost

Is there any design/chip capable of auto-switching from step-up to step down (&vice versa) by detecting the voltage output ?

P.S. I don't want to have inverted output => CUK converter is not preferred.

Any idea?

Re: Buck and boost

SEPIC converters will do either Buck or Boost without inversion.
