EPC CEO & Co-Founder, Alex Lidow delivers a presentation entitled, Silicon is Dead in the Ridley Engineering booth at APEC 2019.
In this episode of PSDtv Alex Lidow, Chief Executive Officer and Co-Founder of Efficient Power Conversion (EPC) is at APEC 2019 in Anaheim and discusses why their GaN on Silicon devices make Silicon now dead.
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.
The EPC2052 offers power systems designers a 100 V, 13.5 mΩ, power transistor capable of 74 A pulsed in an extremely small chip-scale package. In a 48 V – 12 V DC-DC Power Converters these new generation eGaN FETs achieved greater than 97% efficiency at 500 kHz and greater than 96% Efficiency at 1 MHz
EL SEGUNDO, Calif. — March 2019 — Efficient Power Conversion (EPC) announces the EPC2052, a 100 V GaN transistor with a maximum RDS(on) of 13.5mΩ and a 74 A pulsed output current for high efficiency power conversion in a tiny 2.25mm2 footprint.
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?
As part of its continuous support to a widening customer base for DC-DC, LiDAR, wireless power applications and beyond, EPC continues its innovation journey by meeting with engineers in key industry exhibitions worldwide in March and April 2019.
EL SEGUNDO, Calif. - March 2019 — EPC experts are available to meet with innovative engineers interested in incorporating GaN into their designs at key industry exhibitions worldwide in March and April 2019.
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 VIN, 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 17th through the 21st. 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.

EPC’s Phase Ten Reliability Report adds to the growing knowledge base published in the first nine reports. With this report, EPC has stress-tested over 30,000 parts for a total of over 18 million hours without failure. There have been no field failures in over two years despite shipping millions of parts.
EL SEGUNDO, Calif.— February 2019 — EPC announces its Phase Ten Reliability Report, documenting the test results leading to the successful completion of automotive AEC-Q101 qualification. AEC-Q101 demands the highest level of reliability standards for power FETs, requiring not only zero datasheet failures, but also low parametric drift during stress testing. Of note is that EPC’s WLCS packaging passed all the same testing standards created for conventional packaged parts, demonstrating that the superior performance of chip-scale packaging does not compromise ruggedness or reliability.
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.
As an example of the contribution to performance GaN devices can make to one of these mainstream applications, a traditional silicon application, the 12 V – 1 V point-of-load (POL) DC/DC converter will be examined. An eGaN IC based 12 V to 1 V, 12 A load converter yielding a peak efficiency of 78% at 5 MHz with a power density of at least 1000 W/in3, all with a cost below $0.20 per watt will be shown
