Gamers may not care about the finer points of gallium nitride (eGaN) chips as evangelized by power pioneer Alex Lidow, CEO of Efficient Power Conversion (EPC). But they will care that those chips will enable a new generation of gaming laptops with much smaller power supplies than in the past.
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 Vac – 264 Vac). The adapter has a power density of 20 W/in3. This high efficiency means that the device runs cooler than standard AC/DC adapters.
200 V、25 mΩ氮化鎵功率電晶體(EPC2046)比等效MOSFET小型化12倍，可應用於無線充電、多級AC/DC電源供電、機械人應用及太陽能微型逆變器。
宜普電源轉換公司（EPC）宣佈推出面向多種應用的EPC2046功率電晶體，包括無線充電、多級AC/DC電源供電、機械人應用及太陽能微型逆變器及具低電感的馬達驅動器。EPC2046的額定電壓為200 V、最大導通電阻（RDS(on)）為25 mΩ、脈衝輸出電流為55 A。
