I'm developing an AC to DC PFC converter.  For 230v rms input, how do I have to select Vin minimum and Vin maximum? In general for any given circuit, how can I select those values??

Hold on one moment,

Vin minimum and Vin maximum are the RMS line voltages you expect to see in your application, if you're designing for a single source only, line range will have +/-15% limit variance, so you may use 195Vac - 265Vac (+/-15%). Typically, the concern in these cases is to operate through the expected line variation.
