Hi Lin,

Can you share the part number of the inductor.

I would suspect a saturating inductor core as a starting guess.

Thanks,

Avish

Hi Lin,

Apologies for the late reply. What were your input conditions when you saw the hot inductor? Can you also take a scope shot of the inductor current or the current sense pin?

Thanks,

Richard
