Dear TI team,
I'm using TI UCC28070 controller for the PFC application. The aim is to use externa sync function.
I have calculated the RRT and RDMX as per the equations 8 to 10 on page 16 of UCC28070 datasheet.
The synchronization is happening at the desired frequency, however, we have noticed abnormal behavior at 10% higher the set sync frequency.
Could you please provide a direct contact, I'm preparing a report for your understanding with waveforms captured.
Many thanks
Regards
Ram
