hello everybody,
I'm working on a split adjustable switching power supply using LM2678.
Right now I'm just collectiong informations. I already realized quite well
how to build a single adj. supply (reading LM2678 datasheet), but I need
to know how to use the given component for a power supply capable of an
adjustable V from about +/-3V to +/-30V (5A) and couldn't find so far how
to connect the 2678 (or a similar "negative brother") to get dual voltage.
What basically I need is something similar to a split pow.supply made of a
couple of LM317 plus LM337 (but switching and capable of more current).
Can you help me with some links to schematics/appnotes or whatever ?
thanks
