Description
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 reduce power FET stress, reduce switching losses and reduced EMI interference (EMI).The DK87xxAD greatly simplifies system design and manufacture of AC-DC converters, especially those requiring high eff.
