EL SEGUNDO, Calif. — December 2020 — BrightLoop Converters has greatly reduced the size, cost and improved reliability of its latest BB SP DC-DC buck converters thanks to Efficient Power Conversion Corporation’s (EPC) EPC2029 enhancement-mode gallium nitride (eGaN^®) FET transistors. By switching from silicon (Si) transistors to gallium nitride (GaN), BrightLoop was able to increase the switching frequency of their design from 200 kHz to 600 kHz, while keeping the same efficiency. This design change increased the power density of the solution by a factor of approximately two and this resulted in lower cost by enabling the implementation of a smaller enclosure.

EPC’s EPC2029 is an 80 V, 48 A eGaN^® FET featuring a 1 mm ball pitch. The wider pitch allows for placement of additional and larger vias under the device to enable high current carrying capability despite the extremely small 2.6 mm x 4.6 mm footprint.

面向高功率密度且低成本的DC/DC转换，EPC9151功率模块利用EPC2152 ePower™功率级实现性能更高和尺寸更小的解决方案。

宜普电源转换公司（EPC）宣布推出EPC9151，这是一款300 W、双向、超小尺寸的1/16砖型DC/DC降压转换器模块，其尺寸仅为33 mm x 22.9 mm (1.3”x 0.9”)。EPC9151采用Microchip公司的数字信号控制器（dsPIC33CK）和EPC公司的 ePower™ 功率级集成电路（EPC2152），于300 W、48 V/12 V的转换器中，可以实现95％以上的效率，而且可以在这个可扩展的两相设计中增加相数，使得功率可以更高。

美国微芯科技公司（Microchip Technology Inc.）的数字信号控制器（DSC）与宜普电源转换公司（EPC）的超高效氮化镓场效应晶体管（eGaN^®FET）的结合，可实现最佳功率密度（730 W/in³），从而实现高效、低成本的DC-DC转换。

EPC公司宣布推出1/16砖式、300 W DC/DC稳压器（EPC9143）。 EPC9143功率模块把Microchip dsPIC33CK数字信号控制器（DSC）和最新一代eGaN FET（EPC2053）集成在一起，实现25 A、48 V/12 V和96％效率的功率转换。

Efficient Power Conversion (EPC) will showcase the company’s latest ePower™ Stage IC family of products showing how GaN technology’s superior performance is transforming power delivery for computing, communications, robotics, and transportation at the PCIM Europe 2020 Digital Days.

EL SEGUNDO, Calif.— June 2020 — The EPC team will be delivering three technical presentations and participating in two panel discussions on gallium nitride (GaN) technology and applications at the upcoming PCIM Europe 2020 Digital Days, July 7 – 8. In addition, the company will participate in the event’s virtual exhibit, showing its latest eGaN FETs and ICs in customers’ end products that are rapidly adopting eGaN technology.

Over the past decade computers, displays, smart phones and other consumer electronics systems have become thinner while also becoming more powerful. As a result, the market continues to increase its demand for thinner power supply solutions with greater power density. This article examines the feasibility of adopting various non-isolated dc-dc stepdown topologies for an ultra-thin 48-V to 20-V, 250-W power solution.

It’s getting harder to avoid using GaN power transistors and ICs, says Alex Lidow. There are many reasons to use GaN-on-Si power transistors such as eGaN FETs, in telecoms, vehicles, healthcare and computing. Smaller, faster, lower cost, and more integrated, GaN-on-Si devices have spent a decade gaining the confidence and trust of designers across the spectrum of power conversion applications.

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.
