EPC introduces 100 V, 3.8 milliohm EPC2053 eGaN^® FET, joining the EPC2045, EPC2052, and EPC2051 to offer a comprehensive 100 V family of GaN transistors that are more efficient, smaller, and lower cost for high performance 48 V DC-DC conversion.

EL SEGUNDO, Calif. — April 2019 — Efficient Power Conversion Corporation, the world’s leader in enhancement-mode gallium nitride on silicon (eGaN) power FETs and ICs advances the performance capability while lowering the cost of off-the-shelf gallium nitride transistors with the introduction of the EPC2053 (3.8 mΩ, 100 V) eGaN FET.

专为功率系统设计师而设的EPC2052功率晶体管是一种100 V、13.5 mΩ并采用超小型芯片级封装的晶体管，可实现74 A脉冲输出电流。面向48 V-12 V DC/DC功率转换器，这些新一代氮化镓场效应晶体管工作在500 kHz频率下，可实现超过97%的效率。如果工作在1 MHz时，则实现超过96%的效率。

宜普电源转换公司（EPC）宣布推出100 V的EPC2052氮化镓场效应晶体管，其占板面积只是2.25平方毫米、最大导通阻抗(R_DS(on))为13.5 mΩ及脉冲输出电流高达74 A 以支持高效功率转换。

When the issue invariably turns to the packaging of the power semiconductor – transistor, diode, or integrated circuit – the requests for improvement fall into six categories:

1. Can you make the package smaller?
2. Can you reduce the package inductance?
3. Can you make the product with lower conduction losses?
4. Can you make the package more thermally efficient?
5. Can you sell the product at a lower price?
6. Can you make the package more reliable?

New converter topologies and power transistors promise to reduce the size and boost the efficiency of supplies that will run next-generation Artificial Intelligence (AI) platforms. In all the topologies with 48 V_IN, the highest efficiency comes with using GaN devices. This is due to their lower capacitance and smaller size. With recent pricing declines in GaN power transistors, the cost comparison with silicon-based converters now strongly favors GaN in all the leading-edge solutions.

EPC will exhibit live demonstrations showing how GaN technology’s superior performance is transforming power delivery for entire industries including computing, communications, and automotive.

EL SEGUNDO, Calif. — March 2019 — The EPC team will be delivering eleven technical presentations on gallium nitride (GaN) technology and applications at APEC 2019 in Anaheim, California from March 17^th through the 21^st. In addition, the company will demonstrate its latest eGaN FETs and ICs in customers’ end products that are enabled by eGaN technology.

In the final installment of this series, how GaN has met the requirements to displace silicon is explored. As the adoption rate of GaN explodes, it is important to remember that, while GaN has made many advancements in just a few short years, it is still far from its theoretical performance limitations and thus there are profound improvements that can continue to be achieved. In time, the performance and cost advantages of GaN-on-silicon will result in a majority of applications currently using silicon-based devices converting to the smaller, faster, cheaper, and more reliable GaN technology.

继第一至第九阶段可靠性测试报告后，EPC公司的 第十阶段可靠性测试报告进一步丰富知识库。此报告对超过30,000个元件进行了超过1,800万小时的应力测试后，没有器件发生故障。在过去的两年间，我们所付运的数百万个元件没有发生现场失效的情况。

宜普电源转换公司（EPC）发布第十阶段可靠性测试报告，成功通过车规级AEC-Q101应力测试认证。AEC-Q101认证要求功率场效应晶体管符合最高的可靠性标准，不仅仅要求器件符合数据表内所载的条件而没有发生故障，也同时要求在应力测试中，具有低漂移。请注意，EPC所采用的晶圆级芯片规模封装（WLCSP）也符合所有针对传统封装的测试标准，展示出该封装具备卓越性能之同时没有影响到器件的稳固性或可靠性。

In this conference GaN market and technology status will be addressed and its future evolution will be debated by mixing visions from designers, manufacturers, and end users.

EL SEGUNDO, Calif. — January 2019 — Efficient Power Conversion (EPC) is joining forces with Yole Développement (Yole) and SEMI to sponsor the first ever ‘GaN Con,’ an industry networking event covering the entire power GaN industry from manufacturers to end users. The theme of GaN Con is “Power GaN: From promises to possible market explosion” and is focused on the emerging GaN market and the state-of-the-art for its underlying technology.

氮化镓器件对提升主流应用的效率的贡献很大，例如在传统硅基12 V - 1 V负载点 DC/DC转换器。基于eGaN集成电路的12 V转到1 V、12 A负载转换器在5 MHz的频率下，可以实现78%峰值效率及1000 W/in³ 功率密度，而成本则低于每瓦0.2美元。
