Tool/software:

Hello,

I am a thermal engineer and I want to implement TPSM843A26RDGR in my design.

I could not find any thermal resistances in the product datasheet, except for the junction-ambient resistance (I need the junction-board, junction-case-top and junction-case-bottom resistances as well).

I would appreciate if you would provide it.

Thank you!

Thank you for your very quick response.

Do you have any official Texas Instruments document that I can provide as a reference to the values you provided?
