Depending on the conditions of the evaluation, please use an appropriate inductor for the DC superposition characteristics. Otherwise, there is possibility that GaN power transistor is damaged due to large current bym agnetic saturation.. To avoid damaging the GaN power transistor by overheating, please dont apply a constant positive voltage as a clock signal. Please adjust the pulse width so the maximum drain-source current rating is not exceeded.
