AM2432: AM2432 Power Estimate

Hi,

It is not recommended to use the Power Estimation Tool (PET) for supply sizing. PET can be used to estimate average active power and to input total SoC power into thermal simulations. For supply sizing, we recommend using regulators with electrical/thermal spec equivalent (or better) to the PMIC or discrete solution used in the SoC EVM. Alternatively, the maximum current ratings can also be used for supply sizing when designing custom power solution. Here are some reference documentation/tools.    

• AM64/AM243 Power Estimation Tool: https://www.ti.com/tool/download/AM64-PET-CALC
• Maximum current ratings: https://www.ti.com/tool/download/SPRR451
• Recommended power supply implementation:
  • AM64 or AM243-ALV package: TPS65219/220 PMIC https://www.ti.com/lit/pdf/slvafe9
  • AM243-ALX package: LP87334D https://www.ti.com/lit/pdf/SLDA059
• Note: When designing custom discrete power solutions, make sure the discrete components to handle the sequencer, voltage supervisor, and reset logic are included. These are commonly integrated in the recommended TI Power Solution.   

Thanks,

Great, thanks for the resources and the advice on the power estimation. I'll design from the reference implementations and max current ratings. I appreciate the quick response!
