Wolfspeed's Gen 5 SiC MOSFETs are engineered for real-world performance — not just ideal conditions. Built on optimized planar MOSFET design, Gen 5 achieves better RDS(ON) through tightened epitaxy, increased active area, and enhanced soft body diode technology. The result: lower losses, higher reliability, and greater design confidence for automotive and industrial applications.
2.2 kW Bridgeless Totem-Pole PFC
CRD-02AD065N
- Highly efficient and low cost solution of 2.2 kW bridgeless totem-pole PFC topology based on Wolfspeed’s latest (C3M™) 650 V 60 mΩ SiC MOSFETs
- Comfortably achieve Titanium standard by having > 98.5% efficiency while THD < 4% under all load conditions
- Innovative resistor based current sensing solution
- Distortion less inductor current at zero crossing during all load conditions
- Reduced Bill of Material (BOM) by the use of general purpose diodes in place of low frequency switches
- Main target applications of this demo board include: Server; Telecom and Industrial power supply units (PSU)
- Documentation includes bill of materials (BOM); schematic; board layout; application note
