Yessss. I'd been imagining using it for this application but I hadn't actually tested it.
I don't know that an IC like this exists- takes an analog input and turns it into PWM. It's a shame, because it's useful, but it's NOT a shame, because I can sell it.
Pat can use it to control the temp on his hot-wire cutter. For that matter, I can use it on MY hot-wire cutter.
