Worst case internal power consumption for iMX8MQ

Hi,

We are working on iMX8MQ based custom board. We have calculated the internal worst-case power consumption on iMX8MQ processor using NXP iMX8MQ EVK board as a reference. We understand that the typical power consumption depends on the use case.

The EVK power consumption value derived from the above calculation is too high (~14.8W).

 

We found one application note, AN12118, which shows the power consumption of iMX8M processor is <4W.

So we want to understand, why the EVK power distribution is designed for such high power, ~14.8W?

 

We do not want to over budget our power supply design for iMX8MQ processor. 

 

Thanks.
