Dear PI TEAM,
my power supply design specifications are,
Input voltage = 98V DC
output voltage = 60V
output current = 1A.
Isolation is required between Input & Output.so I selected TOP-SWITCH based fly-back topology. I want to use TL431 based secondary feedback.My doubt is at 60V output , the cathode-anode volage of TL431 is around 53V.but the maximum operating voltage of TL431 is 36V only.so plz suggest me how to protect TL431.
