hi every body,
So i find this circuit (flyback power supply 24 V 1 A) which use the ic top255yn from top-switch HX and the transformer MYRRA 74030 so i would to change it with the ic top245yn from top-switch GX,i know for that i need to change R3,R4 and R5 (R6 and R7 i know how to change them) so how i can calculate the values of R3,R4 and R5 to get the same features (Vout,Iout,Pmax).
Cordially.
