TPS84250: Device material for thermal simulation

nirbhay kumar singh
Prodigy 90 points
Part Number: TPS84250 
Hi,

   We are using TI  DC-DC regulator(TPS84250) in one of our design.For thermal simulation following information is required-
1. Material of the device
2. Density
3. Specific heat
4. Melting temperature
5. Resistivity
6. Thermal conductivity

Could you please share these information's to us so the we proceed to the design.

Thank you!

    Hi,

    Let me look into this and see if we might have some information on this. When I get some more information, I'll get back to you on this.

    Regards,

    Hi Nirbhay,

    Because the power module is not a one material / black box, you would need more details on the internal constructions, routing, BOM, power dissipation etc of both IC and inductor to get an accurate thermal model. Unfortunately this is proprietary information that cannot be discussed.

    I can only provide you details on the thermal information which is detailed in Section 4.5 of the datasheet. If you have any specific applications question, please feel free to ask here.

    Regards,

    Jimmy
