Thanks for the response. While UCC28056 can support universal type input ranges from 85Vac to 265Vac, if an application requires wider input voltage range than this (80Vac to 305V for example), UCC28051 would be a better fit.As you noted, the brown-in threshold of the ZCD/CS pin would limit the maximum allowable bulk voltage setting to avoid tripping OVP2 protection.
