Is the source terminal near to the gate a kelvin source?
Hi, and thanks for your good question on the QFN GaN FET, EPC2302.
The Source pin near the gate is not a Kelvin source pin. It is best to connect all of the Source pins on your board together, as a plane. This will optimize the Rds,on of the FET in your design.
As far as connecting a gate driver: run a trace from the Source plane to the gate driver. Connect the trace to the Source plane near the Gate.
For an example: evaluation board part number EPC90133 is a half-bridge layout with this FET. Its home page: https://epc-co.com/epc/products/demo-boards/epc90133
its Gerber files: https://epc-co.com/epc/documents/gerber-files/EPC90133%20Development%20Board%20Gerbers.zip
Best of luck with your design!
