Hello,
I have a TPA3116D2 design with PBTL mode driving a 4 ohm load. I cannot find any examples of how to layout the PCB for this design (using 2 inductors). Specifically I need the design to have good EMC and pass FCC part 15 B. The EVAL board claims to do this but they give no info as to the conditions (PVCC, power output level etc,) and I assume it was not in PBTL mode. Should the routing of the outputs each go to their own snubbers (as on the EVAL board) before bridging together into the inductor? Any advice is appreciated.
Thanks,
Greg
