LM25011 is damaged when Css value increase(0.122uF) at input voltage ON/OFF test.
Do you have any cause that LM25011 is damaged by increasing Css value?
Vin=34V, Vout=26V, Fsw=500kHz, no load condition.
And I would like to know Css discharge function. On datasheet block diagram, I think SS pin has FET for discharge.
When does this FET turn ON? Is there possibility that Css is not full discharged because capacitance value is large, and Vin is added in this condition, then LM25011 is damaged?
