LM5122: Thermal Concern

Part Number: LM5122

Dear Team,

I have some query to discuss with you about Simulation result of LM5122  regarding the Ambient Temperate influencing the load respond.

Refer the snapshot below, you can see that the load respond is fail at condition Ambient Temperature 70C.

May I know the kay factor/parameter that failure this cause concerning to our Ambient Temperature spec is 70C which I’m worry on that.

 

Thank you in advance and hope you can feedback soon.

 

Simulate result with 50C

Simulate result with 70C
