LM5009: LM5009 / Behavior at RCL left open

Part Number:LM5009

Hi,

Now the customer is considering to use LM5009 and estimating the behavior at RCL left open due to soldering failure. I understand that RCL set  the length of off-time, then how does LM5009 behave under over load condition with RCL left open?

Best Regards,
