Jetson NANO power problem!!!

Chuitoto

Hi! we are doing a project need to power up jetson NANO with a 5V 3A capable pwoer bank. Since our Jetson NANO board needs 12V, we add a boost converter in our design.
the logic flow is like this:

PowerBank 5V  ->  5Vin boost converter 12Vout  ->  12V jetson NANO

The problem is when we run some code on Jetson NANO, it's shut down unexpectedly...

We checked the V and I in both path (both PowerBank to Boost && Boost to Jetson) and we found out that the power loss is really high, it hit 50% loss

here is the schematic of our boost converter, are we doing something wrong? 

any suggested solution for this ??

    Hi,

    You may have fried it. Jetson nano uses 5V, it doesn't use 12V.

    Hi shabaz! thnk you for your reply! However, our board is not the standard NVIDIA jetson NANO dev kit. this board is made by 3-party company. So thats why I said using 12V to power it up. 

    and the problem right now is when the currect increase, the efficiency of my boost converter decrease as shown at the video. how thats going to happended...

    You could check your boost converter using a resistor or resistors in parallel, and measure the voltage, to see if the circuit can actually deliver the load or not. The video does not help, it doesn't show anything much. The IC you're using only supports up to 2A max, whereas the Jetson Nano uses more than that if there are peripherals which there may well be on the third party board. The circuit may be badly laid out or the inductor may not support the load. I have no idea because there is so little information.

    In any case, I think you need to reconsider this project, and simply power it from a 12V source (e.g. 12V battery pack) instead of trying to build a high current capable boost converter from 5V to 12V. There are even camera batteries which are 7.2V or so which would have been a better choice than a 5V source.
