Part Number: TMS570LS0432

Hello.

I am building a custom board for TMS570LS0432 IC . I require your help regarding the following issue:

How is the power dissipation of the TMS570LS0432 IC calculated? I require it for thermal design of PCB.

    Hello Kartik,

    The datasheet specifies the following power dissipation models:

    The total power consumption can be computed by summing the power of each of the voltage rails + the sum of the IO loading according to your application. ThetaJA and ThetaJC values are defined in accordance to the JEDEC standard. More information can be found in this TI application note: www.ti.com/.../spra953c.pdf
