DK8712AD Asymmetric Half-Bridge AC-DC Power Converter

DK8712AD Asymmetric Half-Bridge AC-DC Power Converter

The DK87xxAD is an AC-DC power converter based on asymmetric half-bridge topology, which integrates half bridge GaN devices. The DK87xxAD recycles leakage inductance energy to enable primary side ZVS and secondary side ZCS. Therefore, system overall efficiency is improved. Soft switches also can red.
