eGaN FETs and ICs enable very high-density power converter design, owing to their compact size, ultra-fast switching, and low on-resistance. The limiting factor for output power in most high-density converters is junction temperature, which prompts the need for more effective thermal design. The chip-scale packaging of eGaN FETs and ICs offer six-sided cooling, with effective heat extraction from the bottom, top, and sides of the die. This article presents a high-performance thermal solution to extend the output current capability of eGaN-based converters.

From the heart of Silicon Valley comes a new buzzword. Gallium nitride is the future of power technology. Tech blogs are touting gallium nitride as the silicon of the future, and you are savvy enough to get in on the ground floor. Knowing how important gallium nitride is makes you a smarter, better consumer. You are at the forefront of your peer group because you know of an up and coming technology, and this one goes by the name of gallium nitride.

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.

專為功率系統設計師而設的EPC2052功率電晶體是一種100 V、13.5 mΩ並採用超小型晶片級封裝的電晶體，可實現74 A脈衝輸出電流。面向48 V-12 V DC/DC功率轉換器，這些新一代氮化鎵場效應電晶體工作在500 kHz頻率下，可實現超過97%的效率。如果工作在1 MHz時，則實現超過96%的效率。

宜普電源轉換公司（EPC）宣佈推出100 V的EPC2052氮化鎵場效應電晶體，其占板面積只是2.25平方毫米、最大導通阻抗(R_DS(on))為13.5 mΩ及脈衝輸出電流高達74 A 以支援高效功率轉換。

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.
