Hi,

We implemented as per your suggestion ( refer attached is the referenced document which you have advised us), but still it is going into hick up mode.

Requesting to help us to over come this issue.

    I assume you are now running LM5023 in closed loop.

    In section 7.4 (page 18) of the datasheet all the fault conditions that can stop operation are listed.  If it appears that LM5023 is operating in hiccup mode, this could be caused by VCC dropping below VCCOFF or an overload condition exceeds the overload timer duration.  Please confirm that neither one of these events are occurring.

    Best Regards,

    Eric
