Other Parts Discussed in Thread: UCC28C40, UCC28C42, UCC28C43, PMP30720, TL431
Hello E2E,
I used WEBENCH® Power Designer to design an flyback power supply and I selected UCC28C40 PMW controller circuit but before I order the component I want to simulate this circuit using TINA TI to see the real outputs and also to optimize the circuit before manufacturer it.
Here is the circuit link from WEBENCH® Power Designer
https://webench.ti.com/appinfo/webench/scripts/SDP.cgi?ID=6EF06136D7B197F9
I want to have multiple outputs on the circuit for that I modifieded the circuit on WEBENCH and I took the values of Npr and Nsec of the transformer and I used them in my design but I can not take correct outputs, so may you please check my circuit and modify it to make it work.
I am not sure did I used the correct transformer and optocoupler or not please guide me and modified the circuit .
My circuit TSC file is attached.
Sincerely,
Abdelrahman
