Part Number: UCC28710 Other Parts Discussed in Thread: UCC28730 , , PMP40025 Dear All,
one of my customer working on PMP40025 reference design and we suggested to use UCC28710 instead of UCC28730 device for cost optimisation.
Following are the few…
Part Number: PMP40025 Other Parts Discussed in Thread: UCC28730 Hi,
I am working on PMP40025(AC to DC flyback converter) schematics attached , I am trying to fabricate an test the reference design given in TI Website.

Dear Ahmed,
Thanks for promoting our products to the customer!
Base on your customer's circuit most of the time stay in the standby mode, I won't suggest you use SR in your design.
For a high step down flyback circuit, is difficult to have high…
Part Number: UCC28740 Tool/software:
Dear Experts,
At present, we are designing a flyback power supply using UCC28740. The design requirement is to input 300VDC can start, but during actual testing, we found that it cannot start at this voltage. The…
Hello Keshab,
Evidently, there are more issues than just the diode ones that I mentioned.
Please refer to this debug guide to help you get further along with the debug:

Perhaps something in this procedure…
Guifre,
I would suggest maybe reviewing this video about debug of UCC287xx designs:
training.ti.com/getting-started-ucc287xx-family
There is also this debug document that would be useful:
