...FASST does not "brown out" It works down to about 2.8 volts and then stops until it sees greater than 2.8 volts. ...
Bill,
That is EXACTLY the definition of a brown-out!
ALL electronics can be browned-out, your favorite brand included.
Maybe living in CA you're more familiar with black-outs but those are different - power goes to 0. A brown-out on the AC grid is below 85VAC (we call it "low-line").
