UCC2897A feature of low output jitter

Part Number: UCC2897A

Hi Team,

The UCC2897A datasheet shows feature of low output jitter.

Could you please help to explain it? How to enable it?

    Hello Ray Chang,
    Jitter on the output is not something you would wish for in a power supply and anything you can do to eliminate this is greatly appreciated.
    My understanding of the source jitter in an active clamp topology is that it relates to a premature turn on of the clamp FET.
    The UCC2897A allows for a time delay between the main FET turning off and the clamp FET turning on.
    This results in the elimination of a source of output jitter when self driven synchronous rectifiers are used in the output circuit.

    Regards
    John

    Hi Ray Chang,

    Since there has been no activity for a long time on this post, I hope that John has resolved your problem.
    If not, just post a reply below (or create a new thread if the thread has locked due to time-out). Thanks.
