hi,
 by chance has anybody in their travels
done/seen a project or  some code written for a pic. to mimic a
switchmode ic.
i want to use a 12c508 to replace a lm3524 / tl494 ic for my project !.
project/code for any type of pic used in this area would be of
assistance ,& give me something to work from
thanks for your help & time
