Vertical GaN technology power platform allows the smallest, most advanced computer power supply systems, anywhere.

Home Solutions Compute Solutions

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 We have all had to suffer through the pain of traveling with these outdated bricks, lugging them in our back-packs and travel bags.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.
