A Research on High Efficiency InnoSwitch3-EP GaN AC/DC Integrated Circuit

In this paper, application and research issues related to novel quasi-resonant AC/DC integrated circuit with GaN transistors are discussed. The results of the design and investigation of a laptop power supply device with an output power of 65W implemented with INN3679C-H60X of the InnoSwitch3-EP family are presented. The performance oscillograms of the GaN power transistor as well as the input, output and regulation characteristics of the power supply are presented.
