Today, power converters are everywhere. Electronics from LED lighting, electric vehicles, data centers to computers all require relatively bulky AC/DC power converters. The demand for higher performing, more efficient power electronics is growing exponentially, and traditional silicon solutions cannot keep up.
For 20 years, computer power supply units have been bricks.
Power supplies, especially computer power supplies have been large, bulky, heavy, and inefficient. We have all had to suffer through the pain of traveling with these outdated bricks, lugging them in our back-packs and travel bags. Today’s computer platforms have evolved to the point of fitting in our back-pocket, but their power supply units have simply not evolved for decades.

Turns out it’s the technology.

The semiconductor technology at the heart of these power supplies has not evolved since Si Super-junction MOSFETs transformed how transistors conducted current. A simple teardown of a typical power supply shows the root cause of why a power brick is aptly called a “brick”.
Most of the space is taken up by the inductors, capacitors, and transformers because the fundamental switching device, typically a Silicon based power transistor, switching no more than 50-100kHz. Some modern power transistors push this to 200kHz but this does nothing significant to the end power supply size, weight, and efficiency.
Introducing the NexSys 240W Ultra-Compact
A next-generation laptop power adapter with unmatched performance in an unparalleled size

>30% Lighter >15% Smaller >30% Reduced Power Loss
The smallest, most efficient PSU in the world

Compared to typical and best-in-class 230W PSU

Compared to best-in-class 96W PSU
By leveraging NexGen’s Vertical GaN technology, the NexSys 240W provides the industry’s highest power density enabling >15% smaller and >30% lighter size than typical power supplies, and also cuts the power losses by >30%. Compared to a standard laptop power supply, the NexSys 240W provides 2.5x more power in almost the same form factor and weight.
This is enabled by a platform based design that is the world’s first commercial power supply specifically designed to switch at 1-3MHz. In comparison to today’s standards, even best in class, there is no smaller more efficient power supply in the world.
Sampling to lead customers available now with commercial availability late 2022.
