Can the UCC28051 be used for an offline, isolated flyback PFC supply of Vout=
36V and 53W?
Its just that i am concerned about how the opto transistor links in to the
UCC28051 , especially considering the 2.7V overvoltage level on the Vo_SNS pin (pin 1)
I guess, you'll want to disable the OVP function by limiting the voltage from the optocoupler somehow. You also need to enforce a level above enable threshold.
