In the past I have designed boost converters in burst mode, with peak

Outputs: +5 @ 25mA, -5V @ 20mA
Can someone point me to a tutorial?
Thanks!
[Don't point me to an off-the-shelf part. This has to go into a
_custom_ chip... just a little thing... 1mm x 25mm :-]
Hmm, an inch long and a millimeter wide--it's for a robotic cockroach,
right?

Nope. It goes in something that virtually every person owns :-)

So you decided to take someone's advice about what to do with your
design?
Cheers
Phil Hobbs
This is but a small portion of the whole chip. As I said, I have no
experience (*) with PWM'd boost converters, though lots of those with
low output current, running burst mode (they have little or no
stability issues).
As Larkin would snark, If you've got something technical to say, then
say it, otherwise STFU :-{)
(*) Unlike some posters lurking here, I readily admit areas of which I
have little or no expertise. Then I listen, learn and ultimately
become the expert ;-)

Why does a self-proclaimed Master Circuit Designer need a tutorial on
something so basic? And why can't he use Google to find it?
If you were paying attention, and not just out to be a horse's ass,
you'd note that I said I'd done a low current discontinuous _boost_
regulator many years ago, but not done a PWM continuous mode before.
But I am indeed a master circuit designer. SPECIFY me a function and
I can do it. I just didn't (note the past tense) know the intricacies
of fancy boost regulators ;-)
Google yields piles of unqualified crap. Friends give guidance, for
which I am greatly appreciative! You are an enemy out to convince
everyone how brilliant you are, at the expense of anyone who gets in
your way. In fact, you're mediocrity personified. And, if you think
it's so basic, give us all a primer. We're all in need of a good
laugh ;-)
