DRA71: Power consumption calculation

Part Number: DRA71


Hello.

I am trying to calculate the power consumption for SoC DRA710 for one of our projects.

I have seen two reference designs for the processors power supply.

Implementation1: http://www.ti.com/lit/ug/snvu577a/snvu577a.pdf http://www.ti.com/lit/ug/spruif1a/spruif1a.pdf

Implementation2: http://www.ti.com/lit/ug/spruii3/spruii3.pdf

I am interested only in the 2nd stage power supplies because 3.3V and 5V voltages will be supplied from another ECU. Are there any pros/cons for either implementations?

Also, I am trying to calculate the S0C power consumption. In the datasheet it is only mentioned to contact you TI representative. Could you assist me?

Thanks
