50 W、12 V/60 V且基于eGaN^® FET的同步升压转换器采用简单、低成本的拓扑结构，可实现 95.3%的峰值效率和低温升。

宜普电源转换公司（EPC）宣布推出双向降压或反向升压转换器演示板（EPC9162）。该演示板用于同步转换器时采用100 V的EPC2052器件，以及用于同步自举FET电路时，采用EPC2038器件。

This article discusses how GaN-based solutions coupled with digital control increase efficiency, shrink the size, and reduce system costs for high density computing applications like ultra-thin laptops and high-end gaming systems. As computers, displays, smartphones and other consumer electronics systems become thinner and more powerful over the past decade, there is increasing demand for addressing the challenge of thinner solutions while extracting more power out of limited space. To address this challenge, the comparative advantages of various non-isolated DC-DC step-down topologies for ultra-thin 48 V – 20 V power solutions that are designed to fit inside a notebook computer or an ultra-thin display are examined.

Taking advantage of the high performance of eGaN^® FETs, Rompower Energy Systems has announced a reference design for a tiny, 65 W, 94% efficient AC/DC power adaptor for laptops and other mobile devices.

TUCSON, Az. – June 2017 – Rompower Energy Systems, an internationally recognized research and development company in the field of power conversion, announces the availability of technology for an extremely small, highly efficient AC/DC power adapter. In the quest for higher power density, the efficiency of the adapter is critical in order to decrease the heat dissipation. The reference design is measuring just 3.19 cubic inches in size, this adapter provides 65 W of power at greater than 94% efficiency over the entire input voltage range (90 V_ac – 264 V_ac).  The adapter has a power density of 20 W/in³. This high efficiency means that the device runs cooler than standard AC/DC adapters.
