Jetson AGX DC Power supply Voltage and Current Performance Limitations

Do the following USB C performance limitations and Voltage/Current combinations apply to the DC input jack or can we achieve full performance at 12V or 15V using the DC Power jack input alone?

  • 5V/3A: ~50% of the maximum performance ( suitable for low-power applications)

  • 9V/3A: ~70% of the maximum performance (suitable for medium-power applications)

  • 12V/3A: ~80% of the maximum performance (suitable for high-power applications)

  • 15V/3A: ~90% of the maximum performance (suitable for high-power applications)

  • 20V/4.5A: ~100% of the maximum performance (suitable for high-power applications that require maximum performance)

What is the current draw at 12V or 15V full performance?

The provided information does not explicitly state the current draw at 12V or 15V for full performance on the DC Power jack input alone. However, we can infer some information from the provided USB-C performance limitations and Voltage-Current combinations.

The table lists the following Voltage-Current combinations and their corresponding performance levels:

  • 5V, 3A: 50% of the maximum performance (suitable for low-power applications)
  • 9V, 3A: 70% of the maximum performance (suitable for medium-power applications)
  • 12V, 3A: 80% of the maximum performance (suitable for high-power applications)
  • 15V, 3A: 90% of the maximum performance (suitable for high-power applications)
  • 20V, 4.5A: 100% of the maximum performance (suitable for high-power applications that require maximum performance)

Since the DC Power jack input is not explicitly mentioned in the table, we can’t directly determine the current draw at 12V or 15V for full performance. However, we can make an educated guess based on the provided information.

If we assume that the DC Power jack input can provide the same performance levels as the USB-C input, we can estimate the current draw at 12V or 15V for full performance.

For 12V, the table lists 3A as the current draw for 80% of the maximum performance. To achieve full performance (100% of the maximum performance), we would need a higher current draw. However, the exact current draw is not specified.

For 15V, the table lists 3A as the current draw for 90% of the maximum performance. Again, to achieve full performance (100% of the maximum performance), we would need a higher current draw. However, the exact current draw is not specified.

Based on the provided information, we can estimate that the current draw at 12V or 15V for full performance would likely be higher than 3A. However, without explicit information, we cannot provide an exact current draw value.

To achieve full performance (100% of the maximum performance), it’s likely that the DC Power jack input would need to provide a higher current draw than 3A, possibly in the range of 4-6A or more, depending on the specific requirements of the Jetson AGX Orin device. However, this is purely speculative, and the actual current draw would depend on various factors, including the device’s power management system and the specific application requirements.

In summary, while we can make some educated guesses based on the provided information, the exact current draw at 12V or 15V for full performance on the DC Power jack input alone is not explicitly stated and would require further investigation or consultation with the device manufacturer.

Thank you for your LLM answer. Ideally we were looking for specific information as opposed to estimates extrapolated from the USB C power requirements.

Is there anyone from Nvidia directly who is able to give an accurate answer as opposed to an estimates/educated guesses please?

The absolute max on the SYS_VIN_HV rail is 5.4A at 20V per the Jetson AGX Orin Series Data Sheet (Including AGX Orin Industrial):

That comes out to 108W. Using that value for worst-case calculations, the Imax would be 7.2A for 15V and 9A for 12V.
