I am working on a new custom PCB to connect to the B404X with some custom sensors. Previously, we had used a Boron Board to interface with our sensors, but while building in the power delivery architecture, I noticed that the Torex 3.3V Buck Converter (XC9258B33CER-G) is EOL, and there are some discrepancies between the SoM Evaluation Board and Boron Board. Both the designs use this part, though the inductor/capacitor sizing differs between the two.
I was wondering if your team is planning to integrate a new part that we might leverage, as well, to keep the design as consistent as possible? If not, any recommendations or pitfalls to avoid would be great to know, as I am always hesitant to swap out a part known to work. Also, I was wondering what the motivation was on the Evaluation Board for utilizing a 2.2uH inductor, which differs from the 4.7uH, recommended by Torex and used in the Boron design?
The 1A max current output and ripple seems sufficient for our application and works well with our connecting sensors for our Boron-based PCB.
