Hi IgorR
Thank you for reaching out.
The IC is most likely restarting because it has encountered a fault.
Please refer the following debug guides which might be helpful with the debug process.

Part Number: UCC28703 Hello,
I am after a 20mA constant current PWM regulator for an audio class G/H power stage, see the attached schematic to replace linear transistor Q1 & Q2.
Must work from 2 Volts to 300 Volts.
What part do I need?
4000W amp…
Other Parts Discussed in Thread: UCC28704 , UCC28703 , UCC28740 Hi
Are there other benefits to the UCC28704 vs. UCC28703?
We know that the UCC28704 has improved load transient regulation but a lower switching frequency.
thank you

Other Parts Discussed in Thread: UCC28703 , UCC28700 Hello!
I'm using WEBENCH for developing AC-DC power supply device.
I've chosen scheme with UCC28703 , but I can't see the simulation button (nor temperature nor electrical simulation)
Does…
Why there is this discussion?
There are so many questions in the forum related to the startup of UCC2870X or other TI PSR controllers/switchers. We know the anxiety when customer met startup issues. So we develop to try to aim customer on their issues…
Other Parts Discussed in Thread: UCC28703 , UCC28730 Hi
We have a power supply to fail to pass the thermal test. This power supply is based on the PMP4450 (UCC28703) reference design from TI (it is built with exactly components with PMP4450). During the…
Dear Maciej ,
Thank you for the answer. I now tried the Webench tool. It seems to be simple, yes - but it is rather a hassle.
When I type in "AC / 50Hz / 210...240V / 0.05A / 30°C" It just shows the parts UCC28700 ... UCC28703 which are all isolated converters…
Other Parts Discussed in Thread: UCC28700EVM-068 Hi,
Now I'm promoting the UCC2870x that is controller with primary-side regulation to our customer. Then they are asking about accuracy of voltage regulation. In UCC28700EVM-068, it state min/max of Vout…
