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氮化镓功率晶体管(EPC2046)比等效MOSFET小型化12倍,可应用于无线充电、多级AC/DC电源供电、机械人应用及太阳能微型逆变器。
宜普电源转换公司（EPC）宣布推出面向多种应用的EPC2046功率晶体管，包括无线充电、多级AC/DC电源供电、机械人应用、太阳能微型逆变器及具低电感的马达驱动器。EPC2046的额定电压为200 V、最大导通电阻RDS(on)为25 mΩ、脉冲输出电流为55 A。
