Hi team,
Is the conduction period from the previous cycle stored forever?
When returning from a long off period, is the previous conduction period stored?
Best regards,

Hello,
Is the conduction period from the previous cycle stored forever?
No. If the device goes into UVLO it is reset.
When returning from a long off period, is the previous conduction period stored?
If the device goes into UVLO it is reset.

Hi Mike,
My question is about the behavior when the load goes from light to heavy load.
The circuit is ACF and uses UCC28782 on the primary side.
At light load, Toff can reach 200us.
Even if Toff is too long, does information about the previous conduction period remain when the next turn on?
Hi Mike,
Thank you, I understand the specifications.
Are there any constraints on the conduction time stored in memory?
