We are trying to test the working of the Pspice model of UCC28C45in TINA for which we build the open loop laboratory test fixture…
Hi Zaim,
You shouldn't need capacitor C20. It slows down the control loop and is one of the root causes of the issue you originally reported.
The control method you implemented has 2 issues:
1) The control topology used around the TL431 is Type…

Part Number: UC3845 Tool/software: Hi,
I'm looking to design a DC/DC buck converter that takes 30V to 100vV input and steps it down to 12V, 12A output.
Are there any reference designs or application notes I can leverage from?
Regards,
Logesh …

Hi Sir,
I am working on a UC1845A IC for offline flyback AC-DC where turns ratio is 5 and Np is 30 Ns is 6 turns.
its just like the application circuit…
