Texas Instruments (TI) has recently released a new series of low-power gallium nitride (GaN) products, which have high power density, high system efficiency, and miniaturization characteristics, helping consumer power electronic devices and industrial systems achieve higher performance and smaller volume.

These new products include GaN FETs with integrated gate drivers, which can solve heat dissipation design problems, keep the adapter cool, and provide higher power in smaller sizes. This series of products includes LMG3622, LMG3624, and LMG3626, which have ultra precise integrated current detection capabilities and can achieve efficient current detection without the need for external shunt resistors, reducing related power losses by up to 94%.

These new products can also help designers improve the system efficiency of AC/DC applications below 75W to 94%, and AC/DC applications above 75W to over 95%. Compared to silicon-based solutions, the new device can reduce the size of a typical 67W power adapter solution by up to 50%. In addition, these products have been optimized for various common topology structures, such as quasi resonant flyback, asymmetric half bridge flyback, inductor inductor converter, totem pole power factor correction, and active clamp flyback.

Texas Instruments has a long-term investment and rich experience in the field of gallium nitride manufacturing. Its own manufacturing bases are located worldwide and exhibit regional diversification. Over the next few decades, Texas Instruments plans to manufacture over 90% of its products in-house, providing customers with more reliable production capacity. These new products can help designers apply the power density advantages of low-power GaN technology to more everyday products used by consumers, such as phone and laptop adapters, TV power units, and USB wall sockets. In addition, Texas Instruments' product portfolio can also meet the growing demand for efficient and compact designs in industrial systems such as power tools and server auxiliary power supplies.

Kannan Soundarapandian, General Manager of High Voltage Power at Texas Instruments, stated: Nowadays, consumers need energy-efficient power adapters that are smaller, lighter, more portable, and can charge quickly. With our new product release, designers can apply the power density advantages of low-power GaN technology to more products that consumers use daily, such as handheld and laptop adapters, TV power units, and USB wall sockets. In addition, Texas Instruments' product portfolio can also meet the needs of power tools and services The increasing demand for high-efficiency and compact designs in industrial systems such as auxiliary power supplies for servers.
