📥 Download Datasheet

General Description

DK0xxG series is a high performance AC-DC power converter with 650V GaN HEMT device integrated.

With quasi-resonant control mode, DK0xxG series can detect the voltage over drain-source voltage across the GaN device and turn on the device when VDS oscillate to the lowest point.

Thus, system overall efficiency and EMI performance can be greatly improved.
