Jetson shutdown at 12V during benchmark

Hello,

I have read on this forum and in the documentation that the Jetson AGX Xavier can be powered on 12V and everything should work. However, when I run the Jetson Benchmark (GitHub - NVIDIA-AI-IOT/jetson_benchmarks: Jetson Benchmark), it only works with the provided 19V transformer. If I power the dev. kit in 12V with my 20A power supply, as soon as the current gets over ~2.2 - 2.5 A the dev. kit kills itself.
The same is true no matter if I power it using the back USB C port or the power Jack.
On the dev. kit, it is written: Input 9V 10A - 20V 4.5A, but that seems to be a lie.

Do you know if I can increase the current limit to be more than 2.5A ?

Thank you

Hi, please read the chapter DV/Dt Circuit Considerations in Product Design Guide.

Jetson AGX Xavier supports from 9V to 20V on the SYS_VIN_HV input.
The higher the voltage used, the lower the current at the input. When large power changes
occur during heavy computational loads, the effect on the supply voltage will be lowest
when the input voltage is near the maximum.
