UCC28C42: TINA Simulation

Part Number: UCC28C42
Other Parts Discussed in Thread: TL431

UCC28C42 has existing Pspice simulation, is it possible to transfer it from Pspice to TINA simulation? Could you guide how to do it? Very thanks.

Hi Brian,

From what I can tell, there is a steady state TINA model and Start-up TINA model available on the "Design & development" tab for UCC28C42. Is this what you need?

Hello Ben,

Thanks. I have downloaded it and open the simulation tool. but i don't see the feedback loop as TL431 + Opto on this tools. Is there any complete one you can offer for engineer's simulation? Very thanks.

Hi Brian,

It should be possible to add the TL431 TINA model into the UCC28C42 TINA simulation and build an isolated feedback network. You could model the opto-coupler as a current controlled current source.

Best Regards,
