Texas Instruments (TI)'s gallium nitride (GaN) technology is featured in Chicony Power's latest laptop power adapter, maximizing the power density and efficiency of Chicony Power's power solutions.


TI Korea (CEO Joong-Seo Park) announced on the 15th that Chicony Power has adopted its integrated gallium nitride (GaN) technology for its latest 65W laptop power adapter, Le Petit.

By adopting TI's LMG2610, which integrates a gate driver into a half-bridge GaN FET, and TI and Chicony Power collaborated to design a power adapter, the size was reduced by 50% and efficiency was increased up to 94%.

Chicony Power is committed to improving power conversion efficiency in electronic device designs and works closely with IC companies to provide solutions that meet market requirements.

To design its latest Le Petit laptop adapter, Chicony Power collaborated with TI, which has expertise in high-voltage design and integrated GaN technology.

TI's LMG2610 pairs with the UCC28782 active clamp flyback (ACF) controller to provide an easy-to-use, power-efficient, and high-density solution for AC/DC designs below 75 W.

Consumers increasingly want smaller and lighter electronic devices, while also being more energy-conscious.To meet these demands in the laptop power adapter market, engineers are faced with the challenge of developing efficient adapters that can deliver more power in a smaller space while minimizing power loss.

TI's LMG2610 GaN FET, which integrates upper and lower switches, gate driver ICs, level shifters and bootstrap circuitry on a single chip, combined with Chicony Power's expertise in 3D structures, component miniaturization, heat dissipation systems and electromagnetic interference (EMI) suppression design, reduces the size of power adapters and reduces material use by up to 40%.

The Le Petit power adapter measures 49cm3, making it compact and slightly larger than a typical ice cube, and can achieve up to 94% power conversion efficiency, compared to the 89% offered by conventional silicone power adapters.

“Our collaboration with Chicony Power demonstrates how TI products enable designers to design smaller, more energy-efficient and more reliable electronic devices,” said Luke Lee, vice president and general manager of TI Asia Pacific and president of Taiwan, Korea and South Asia. “TI’s highly integrated GaN technology enables power adapters to achieve improved thermal performance and power efficiency, while increasing power density using fewer components.”

“Chickoni is deeply aware of its corporate social responsibility and has been adhering to the Responsible Business Alliance’s (RBA) Code of Conduct for many years,” said Winson Huang, Chief Purchasing Officer of Chicony Power. “Our collaboration with TI to develop the next-generation power adapter not only makes it lighter and more convenient than the existing 65W adapter, but also combines the strengths of both companies to improve energy efficiency.”
