Part Number: TPS2023

Hi,

Good day!

Our customer have requested the Theta jc for TPS2023D in SOIC-8 package. We will appreciate if you could provide us this information. 

Thank you and have a great day.


Regards,

    Hi Cedrick,

    Below data is from datasheet.

    But it's just for reference.

    The thermal resistance is depending on layout which vary a lot.

     

    For TI's policy, I will first click resolved button.

    If you have any other concern, contact me any time.

    If you think resolved, please help click'Issue is solved button'.

    Thanks.

    Hi Ziv,

    Thank you for your response. 

    However, our customer is looking specifically for the "Theta JC" of the TPS2023D. Do you have typical values for RθJC? We would appreciate if you could provide this information. 

    Have a great day!


    Regads,

    Hi Cedrick,

    I don't have the parameters.

    The thermal resistor is just for reference according to JEDEC standard and just for reference. You can't use the reference parameters to calculate the thermal rising. 

    The real thermal resistor should have a test. If you really care about this parameters, you can submit a ticket to let the thermal team to have a test.

    The PCB layout influence a lot about the thermal parameters.

    If you have any other concern, contact me any time.
