I am doing PCB layout for a design using the UCC28780. The primary side circuitry is identical to the EVAL PCB: UCC28780EVM-002 using GaN.
I would like to use the SOIC-16 package because I think it will be easier for prototyping and troubleshooting, since the pins are exposed, and I don't need special soldering tools to desolder it.
The EVAL PCB uses the WQFN-16 package. I am nervous about using the SOIC-16 package because it seems that a lot of care went into the EVAL PCB layout (judging from the layout guidelines) and many nodes are critical due to the high switching speeds of the GaN devices. Will I get into trouble using this package or should I be able to get it to work properly as long as I carefully follow the layout guidelines and good practices.
If you think the SOIC-16 is too risky, I will use the WQFN-16.
Thank you for your advice.
