voltage regulator help - ot

[Acetronics2]

You'll be surprised what increase (or decrease) in efficiency you get by simply changing a capacitor or inductor.

I have spent days with winding my own inductors on different cores to get maximum efficiency over the full Input voltage and output current range.

Hi, Ralph

you're right ... new design = "some" windings to try !!! I also appreciated your converter.

by the way ... Would you know a replacement part for the MAX 879 ( low power, low voltage Step up/ Step down ) ... ???

It was a jewel for my 4 cells to 5 v applications, but no more produced now ...
