The latest Rompower technologies reduce the size of the 65 W Laptop Adapter to the size of an AC power plug

The ac/dc adapter technology has evolved over the last years and presently the technologies developed by Rompower Energy Systems Inc., increase the efficiency from 88% to 94%, the highest in its class. This increase in efficiency decreases the power dissipation by more than 50% making the adapter to run much cooler. Lower heat dissipation allowed Rompower engineers to reduce the size of a 65W laptop adapter to a tiny volume of 2.3 inc³ (38.5cm³) comparable with the AC power plug while eliminating the bulky AC cable.

“We always push ourselves to be at the forefront of power conversion technology “says Ionel “Dan” Jitaru the founder and CEO of Rompower Energy Systems Inc.

This outstanding achievement was made possible by the use of intelligent power processing facilitated by Infineon XDP™ digital power controller together with Rompower innovation in topology and magnetics Read more…
