Other Parts Discussed in Thread: TL431
I am working on designing the Isolated converter of 48V/14V using UCC2897A. I was simulating the TINA model available on the website.
Even with the changed values for the required specifications output is not reaching 14V.
Below are the changes I did and tried simulating.
1) Resistor divider values for TL431
2) Transformers turns ratio
3) Even with the above-made changes, I am unable to get the required output voltage. I added a resistor divider and given the voltage at the feedback pin between (2.5V to 5V). even then voltage doesn't reach to 14V.
I even tried replicating the design available in the below-mentioned link. but I was using diodes instead of Mosfets on the secondary side.
Please help me with the issue.
