In the past I have designed boost converters in burst mode, with peakcurrent control, but never with a PWM-controlled loop.Outputs: +5 @ 25mA, -5V @ 20mACan someone point me to a tutorial?Thanks![Don't point me to an off-the-shelf part.

Not everthing, but continuous-mode, PWM controlled boost has been done for about 0.4 century now. I doubt there's anything patentable that somebody hasn't done already.

I've done it a bunch of times, including boosters that transitioned from discontinuous to continuous as the load increased. I've met people who were horrified of continuous-mode boost; don't know why they were. It's really nice and clean and doesn't need snubbing. Just avoid the singularity.
