Carrier board design


I am developing a custom carrier board to interface two imaging sensors and a couple of I/O lines. I see in the P2597_C02_OrCAD_schematics.pdf from the TX1/TX2 developer kit carrier board schematics that it uses the APW8805QBI-TRG DC/DC converter. I can’t find the chip on any reputable distributor shown in Octopart, they’re only available through Ebay/AliExpress. Since the schematic is easy to work with, I could just swap it with a matching TI converter.

My question is if NVidia has a recommended alternative to this chip

the IO POWER design solution on carrier board can be defined base on customer requirement , so you can use other IC as long as the power can meet your board requirement.
