Notes
Why it is interesting: switching dv/dt is deliberately limited to < 10 V/ns for motor insulation and EMI, which shows that GaN in drives is about dead-time and distortion rather than raw edge speed. The board can also be configured as a multiphase buck.
Watch out: obsolete; EPC recommends EPC9193. Current ratings conflict between sources: the product page gives 28 A_pk / 20 A_rms, while the launch press release gives “tested up to 50 A_pk”. The product-page values are used.
