EPC2105 GaN half bridge offers power systems designers a solution that increases efficiency and power density for complete buck converter systems approaching 98% at 10 A when switching at 300 kHz and converting from 48 V to 12 V, and 84% at 14 A when switching at 300 kHz and converting from 48 V to 1.0 V.

EL SEGUNDO, Calif. — November 2014 — EPC announces the EPC2105, 80 V enhancement-mode monolithic GaN transistor half bridge. By integrating two eGaN^® power FETs into a single device, interconnect inductances and the interstitial space needed on the PCB are eliminated. This increases both efficiency (especially at higher frequencies) and power density, while reducing assembly costs to the end user’s power conversion system. The EPC2105 is ideal for high frequency DC-DC conversion and enables efficient single stage conversion from 48 V directly to 1 V system loads.

In this installment of the ‘How to GaN’ series we will discuss a new family of eGaN FETs that is keeping Moore’s Law alive with significant gains in key switching figures of merit that widen the performance gap with the power MOFET in high frequency power conversion.

EPC2025 GaN power transistor offers power systems designers a 300 V power transistor capable of 2ns rise times for high frequency DC-DC converters and medical diagnostic instruments.

EL SEGUNDO, Calif. — September 2014 — EPC announces the EPC2025, a 300 V power transistor for use in applications requiring high frequency switching in order to achieve higher efficiency and power density. Applications enhanced by higher switching speeds include ultra-high frequency DC-DC converters, medical diagnostic equipment, power inverters, and LED lighting.

Gallium nitride (GaN) is one of the technologies that could well displace silicon MOSFETs in the next generation of power transistors. As silicon approaches its performance limits, GaN devices conduct better and switch faster. In this short podcast, Alex Lidow talks about the differences between GaN and silicon power devices.

Long talked about, wide bandgap gallium nitride-on-silicon (GaN-on-Si) transistors are now commercially available. They are being touted for replacing silicon-based MOSFETs, which are turning out to be inefficient for many high-performance power supply designs. Recently, several suppliers of GaN-on-Si-based HEMTs and FETs have emerged in the marketplace, among them Efficient Power Conversion (EPC). To expedite the evaluation of eGAN FETs for power supply designs transitioning from silicon MOSFETs to eGaN FETs, EPC has released several development boards in the last few years.

EL SEGUNDO, Calif.—June, 2014 — Efficient Power Conversion Corporation (EPC) today announce the introduction of demonstration boards for wireless power transfer in an innovative high performance topology; Zero Voltage Switching (ZVS) Class-D. The EPC9506 and EPC9507 amplifier (source) boards utilize the high frequency switching capability of EPC gallium nitride transistors to facilitate wireless power systems with greater than 75% efficiency.

Overall, 2020 could see an estimated device market size of almost $600M, leading to approximately 580,000 x 6” wafers to be processed. Ramp-up will be quite impressive starting in 2016, at an estimated 80% CAGR through 2020, based upon a scenario where EV/HEV begins adopting GaN in 2018-2019. The power supply/PFC segment will dominate the business from 2015-2018, ultimately representing 50% of device sales. At that point, automotive will then catch-up.
