The EPC9171 evaluation board converts 90 – 265 V universal AC input to a DC output voltage adjustable over a wide range of 15 V through 48 V. This reference design can supply 240 W maximum output power at 48 V output voltage and 5 A load current. 

EL SEGUNDO, Calif.— March, 2022 — EPC announces the availability of the EPC9171, a 90 V – 260 V universal AC input to 15 V – 48 V DC output power supply designed for USB PD3.1 ultra-fast chargers. This reference design can deliver 240 W maximum output power at 48 V output voltage and 5 A load

The EPC9165 is a two-phase, regulated output voltage, 48 V – 14 V bidirectional converter that delivers 2 kW with 96.8% peak efficiency

EL SEGUNDO, Calif.— February 2022 — EPC announces the availability of the EPC9165, a 2 kW, two-phase 48 V – 14 V bidirectional converter that operates with 97 % peak efficiency in a small footprint. This solution is ideal for high-density and high-power 48V battery packs such as those required for eMobility and light mobility.

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.
