Texas Instruments releases new low-power gallium nitride series products that can reduce the size of AC/DC power adapters by half

【Lansheng Technology News】Texas InstrumentsIncorporated today announced a new family of low-power gallium nitride products that can help increase power density, significantly improve system efficiency, and reduce the size of AC/DC consumer power electronics and industrial systems. Texas Instruments' entire line of GaN field-effect transistors integrate gate drivers to solve common thermal design issues, keeping adapters cool while delivering higher power in a smaller form factor.

The new GaN FET portfolio with integrated gate drivers includes the LMG3622, LMG3624 and LMG3626, providing the industry’s most accurate integrated current sensing capabilities. Integrated current sensing eliminates the need for external shunt resistors and reduces associated power losses by up to 94%, helping designers significantly improve efficiency compared to traditional current sensing circuits using discrete GaN and silicon FETs.

Dramatically improve energy efficiency and simplify thermal design

TI's GaN FETs with integrated gate drivers enable faster switching speeds, helping to prevent adapters from overheating; also enable designers to increase system efficiency to 94% for AC/DC applications less than 75W, and up to 94% for AC/DC applications greater than 75W. System efficiency for DC applications is increased to over 95%. Our new devices help designers reduce the size of typical 67W power adapter solutions by up to 50% compared to silicon-based solutions.

The product portfolio also targets topologies common in AC/DC power conversion such as quasi-resonant flyback, asymmetric half-bridge flyback, inductor-to-inductor converter, totem pole power factor correction and active clamped flyback ) has been optimized.

Long-term investment in gallium nitride manufacturing

Texas Instruments'own manufacturing history is long-standing, global and regionally diversified, including multiple wafer fabrication plants, packaging and test plants, as well as bump processing and wafer test plants at 15 manufacturing sites around the world. For more than ten years, Texas Instruments has been committed to the research and development of gallium nitride technology.

Texas Instruments plans to manufacture more than 90% of its products by 2030, giving customers more reliable capacity for decades to come.
