WEBENCH® Tools/LM5017: How to identify LM5017 work mode?burst mode or normal mode

Part Number: LM5017

Tool/software: WEBENCH® Design Tools

Hi,

There are different work modes (burst mode and normal mode with the same loading) in the same batch PCBA of LM5017. So, I adjust the frequency from 500K to 100K, the board cank work in normal mode. But how can I make sure sure all the board with same loading can work in the same mode? Could you tell me how to calcuate the threshold value from burst mode to normal mode.

 

 

Thanks  a  lot!

Best Regards!

Sandy
