Thanks. Slurped it off the page and put it in my sim directory.
Behavioral is what you have with all those Linear Technology parts and I've found quite a few boo-boos in those. But they are blazingly fast and sometimes that's more important. Simulating an upchuck episode on a buck converter is kind of impossible with a real device-level model for the PWM chip. At least when you want the sim to finish some time today.

Could get boring, doing your sound effects that slowly. ;)

Hmm.. I tried this one, and it shows about 1.5usec to get up to 5mA with a fast ramp of 2 volts per microsecond (overshoot from 5V to 8V).
With the slow 10mV/usec ramp, it only overshoots about 100mV (~10usec to get up to 5mA).
Quite different, and probably acceptable for a crowbar provided there's a biggish cap on the power supply rails (and no 5.5V abs max parts).
