Hi,
AEC Grade 1 means the ambient temperature is -40 to 125°C.
So the operating junction temperature should be above 125°C due to the power dissipation in the IC.
But in TPS65400-Q1 datasheet the operating junction temperature is mentioned as -40 to 125°C which is conflicting the AEC Grade 1 standard.
Please clarify the what is the correct operating junction temperature range.
This is very critical for our design to qualify this IC.
