Enhancement-mode gallium nitride (GaN) transistors have been commercially available for over five years. Commercially available GaN FETs are designed to be both higher performance and lower cost than state-of-the-art silicon-based power MOSFETs. This achievement marks the first time in 60 years that any technology rivals silicon both in terms of performance and cost, and signals the ultimate displacement of the venerable, but aging power MOSFET.

Ashlee Vance at Bloomberg Business profiles EPC. Silicon has enjoyed some serious staying power. For going on 60 years, it’s been the semiconductor of choice at the heart of transistors—the tiny switches that power the Information Age. A valley has been named after it. Many billion-dollar empires have been forged from it. And now—look away, silicon—it may finally be on the verge of being replaced.
EPC9106 Class-D audio amplifier reference design, using high frequency switching gallium nitride power transistors, demonstrates efficiency enhancement, size reduction and eliminates need for a heat sink while delivering prosumer quality sound.
EL SEGUNDO, Calif. — February 2015 — Efficient Power Conversion Corporation (EPC) introduces the EPC9106, a reference design for a 150 W, 8 ohm Class-D audio amplifier.
Speaking from an industry perspective, technologies only exist for as long as they yield the benefits and capabilities that promise man a certain advantage. That said, mainstream silicon CMOS technology has afforded the industry immeasurable gains that it has thoroughly benefitted from. The question now is this. Is the sun shining down on CMOS ready to set? An emerging class of GaN power chips is finally knocking down the final cost barriers to their adoption. The chips will enable a wide range of applications from wireless charging to autonomous vehicles and more efficient cellular ...
