The power supply has a small board holding the control circuitry. This board compares the voltages against a reference to generate the feedback signals.
I am curious how the board stores a reference voltage, if anyone knows. Dissimilar metals?
Check out footnote 8, which mentions the voltage reference, and has a link to another of his posts which has information about just that component: http://www.righto.com/2014/05/reverse-engineering-tl431-most-common.html
Neat, thanks.
