Hi Experts.
Hello, I would like to design a flyback topology using UCC28740 and the efficiency of the topology should be as high as possible.
Some parameters are as follows:
Vin =350V~390V DC,
Vout= 48V
Iout=5A
When I went through the datasheet of UCC28740, I wonder how to set the values of parameters.
how to set the value of t(resp)?
how to set the value of q(G)?
how to set the values of Iauxnl(max),t(ov),V(VDDFL)?
How to set the value of 
?
Thank you!
