Rompower Announces The AC/DC Laptop Power Adaptor Technology Capable of 94% Efficiency, 20 W/in3 Power Density in an Incredibly Small Package

Rompower Announces The AC/DC Laptop Power Adaptor Technology Capable of 94% Efficiency, 20 W/in3 Power Density in an Incredibly Small Package

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.
