Currently, I am developing a carrier board for Jetson Orin Nano/NX with reference to “P3768_A04 concept schematic” and “P3768_A04_OrCAD_schematics(base_version).pdf”.
So, I have a question about “PRE-REG 5V DCDC” on page 9 of “P3768_A04 concept schematic”.

  1. Is 9V to 20V used as the power supply voltage (DCIN) for this circuit?

  2. R391, R393, and R398 are not installed around p21(VCC) of U3(GS9230NVTQ-R).
    This means that p21(VCC) will not be powered, but is this okay? Or is power being supplied to p21(VCC) from somewhere?

thank you.

I also have an additional question about “PRE-REG 5V DCDC” on page 9 of the “P3768_A04 concept schematic”.

3.R388 is not installed, 9V to 20V is connected to p2 (EN) of U3 (GS9230NVTQ-R), but is this okay?

I was unable to obtain the GS9230NVTQ-R, so I am using the AOZ2264QI-11 according to “Main 5.0 V Pre-regulator: GS9230 (or A0Z2264)- Provides VDD_IN to module” on page 7 of “Jetson-Orin-Nano-DevKit-Carrier-Board-Specification_SP-11324-001_v1.2.pdf”.

Thank you in advance.

VDD_CVB is voltage input to this regulator (9V-20V). Please refer to GS9230 data sheet for further details. Pin 21 is Internal Linear Regulator Output. Pin 2 (EN) voltage is within operating range.

Use of AOZ2264 should be OK, but please check the device data sheet for further details.

Thank you for your reply. I understand.
When I searched online for the “GS9230 datasheet”, all I could find was a one-page PDF with just an overview and no information about the pin configuration.
Could you please send me the “GS9230 datasheet” or tell me the URL where I can get it?
Thank you in advance.

Plese get the data sheet directly from the device vendor. http://www.gstekic.com/product_list_en.php?product_major_id=26
