Infineon Technologies AG developed the new 700 V CoolMOS P7 family to serve today’s and tomorrow’s trends in quasi resonant flyback topologies. These new MOSFETs offer unmatched performance improvements compared to currently used superjunction technologies. Soft-switching topologies like smart phone and tablet chargers but also notebook adapters profit from this advantage. Additionally, the new CoolMOS supports fast switching and high power density designs for TV adapters, lighting, Audio, and Aux power. The new family conveys an improved form factor for very slim designs.
