TPS54622: Maximum ambient operating temp

Dan Andersen

Part Number: TPS54622

What is the maximum ambient operating temperature we recommend for the TPS54622? I see it has a 150C Tj limit, but typically this is much higher than what is allowed (and took qual testing data on) for ambient... I can't find this in the datasheet anywhere.

Thanks,

Dan

Hi Dan,
I don't directly support this device, but would suggest checking figures 40&41 in datasheet.
This should give you an idea of maximum ambient temperature under certain operating conditions (power dissipation) that device can operate without exceeding max of 150Tj.
Hope this helpsRegards

To add onto this, WEBENCH would be the recommended way to get power dissipation in different operating conditions.
