TPS5450: Thermal performance

Part Number: TPS5450

Tool/software:

Hi team,

Do we have any thermal test data with TPS5450 for below operation conditions? Is there any thermal risk if customer uses TPS5450 with below conditions?

Input: 24V

Output: 15V with 40W

Ambient temp: 70 degree (Max)

Best regards

Shuai

  • Hi Shuai,

    The device was characterized to function under these conditions:

    The risk with the conditions listed below is if there is enough copper PCB area to cool down the device enough to function below 125C junction. How much PCB board area will your customer use in their application?

    Thanks,
    Andrew
