The partners leveraged TI’s dual-chip LMG2610 Gallium nitride FET; miniaturized the power adapter design and lower the use of mechanical materials by 40%
Chicony Power recently announced its collaboration with semiconductor solutions leader Texas Instruments (TI) to roll out Chicony Power’s latest 65W laptop power adapter, Le Petit, featuring TI’s GaN technology. Chicony leveraged TI’s half-bridge GaN FET with an integrated gate driver, LMG2610. The official communication noted that the companies collaborated on a design to reduce the size of Chicony’s power adapter by 50% and increase efficiency by up to 94%. TI’s LMG2610 is designed to be paired with the UCC28782 active clamp flyback (ACF) controller to create an easy-to-use, high-efficiency, and high-power-density solution for AC/DC designs under 75 W.
The companies noted that they were able to miniaturize the power adapter design and lower the use of mechanical materials by 40% by leveraging TI’s LMG2610 GaN FET, which integrates upper and lower switches, gate driver IC, level shifter and bootstrap circuits on a single chip, as well as Chicony Power’s 3D structure, component miniaturization, heat dissipation system and electromagnetic interference (EMI) suppression design expertise.
Notably, Le Petit has a compact size of 49 cm3, slightly larger than a typical ice cube, with a power supply conversion efficiency as high as 94% compared to the 89% efficiency achieved by typical power adapters using silicon materials.
TI’s vice president for Asia and president for Taiwan, Korea and South Asia, Luke Lee stated, “Our collaboration with Chicony Power is an example of how TI’s products help make electronics smaller, more energy-efficient and more reliable. Our highly integrated GaN technology enables power adapters with improved thermal performance and power efficiency while delivering high power density with fewer components.”
Chief procurement officer at Chicony Power, Winson Huang said: “Chicony has been committed to corporate social responsibility and has been implementing the code of conduct of Responsible Business Alliance (RBA) for many years. The collaboration with TI to develop a new generation of power adapters will not only provide consumers with lighter and more convenient devices, compared to other 65-W adapters in the market but also use the advantages of both parties to jointly create more energy-efficient products.”
Founded in 1930, Texas Instruments Inc. is a global semiconductor company that designs, manufactures, tests and sells analogue and embedded processing chips for markets such as industrial, automotive, personal electronics, communications equipment and enterprise systems.
Chicony Power is a leading power supply provider working to improve the power conversion efficiency in electronic power designs. The 2008-born company says that it has worked closely with international IC companies, providing them with the market and technical requirements to help develop solutions in new designs.
