I need someone expert or rather familiar with the UC3842 to help clarify.
Based on the following,
http://danyk.wz.cz/uc3842_2.pdf
Page 7
if I were to change my input value from vac 160-270 and output should be 55v 4a(this is separately based on transformer design),what are the values of R and C that should be changed surrounding the 8 pins of UC3842?
Is there any recommended secondary feedback voltage regulator that is optically isolated with example design available?
