The Development Trend of GaN USB Charger

GaN (gallium nitride) power chargers had a significant presence at CES in 2020 – signalling that this year will see widespread interest and adoption in these smaller, faster charging, and more energy efficient devices. Halfway through the year, there is a lot of evidence this is the case. The proliferation in numbers and unprecedented levels of use of the average consumer’s electronic devices has placed market pressure for a more effective and practical design solution from the industry.

With the average American household now containing at least five connected electronic devices and adults alone spending more than six hours per day with digital media, there is a significant increase in expectations around charging capabilities and performance.

GaN technology is uniquely positioned to deliver on this market opportunity – exceeding legacy silicon semiconductor solutions. That’s good news for the innovation reputation of the global market for chargers that is forecasted to reach $25 billion by 2022.

As the performance capabilities of devices from phones to laptops increase, so too does their need for increased levels of power. And yet the fact that they are mobile devices places additional pressure on decreasing the size and weight of their power chargers. While using sleek and ultra-light laptops, phones, and handheld gaming devices, users are no longer willing to tolerate heavy, bulky power bricks. Using GaN technology, chargers shrink in both size and weight while still meeting, or exceeding, the high-power needs (even 100W or more) of today’s devices.

GaN technology is more efficient at converting power, which means that less energy is lost to heat. This means that the design of GaN power chargers uses smaller, lower cost components, transformers, and heatsinks than silicon transistor-based chargers, yielding a smaller size charger with the same, or more, capabilities of the bigger ones.
