GreenBridge™ Quad-MOSFET Solutions

Higher Efficiency, Better Thermal Performance

GreenBridge™ active bridge quad-MOSFETs lower conduction losses and improve power conversion efficiency in a smaller form factor for high-power PoE applications. The FDMQ8205 family is comprised of two N-channel and two P-channel 80V-rated MOSFETs in a single, small MLP-12 package.

With improved conduction loss and superior efficiency compared to a conventional Schottky bridge, GreenBridge solutions provide up to 10 times better power dissipation. A novel self-driving technique eliminates the need for external drive components which reduces solution size, cost and complexity in active bridge applications.
