Texas Instruments (TI) has actually introduced a brand-new lineup of gallium nitride (GaN) items. This new low-power GaN series will help engineers develop incredibly small and efficient AC/DC charging systems that exceed a 95% efficiency rating.
Texas Instruments low-power GaN series has made its debut to meet customers’ demand for power adapters that are more portable, lighter, and smaller. Additionally, the new product portfolio aims to be highly energy-efficient while offering a quick charging solution.
The general manager of the High Voltage Power Supply Division in Texas Instruments, Kannan Soundarapandian, states, “With the expansion of our portfolio, developers can bring the power-density benefits of low-power GaN technology to more applications that consumers use every day, such as mobile phone and laptop adapters, television power-supply systems, and USB wall outlets.”
In the new portfolio of low-power gallium nitride items, there are the LMG3624, LMG3622, and LMG3626 field-effect transistors with integrated gate drivers. All of them provide the most precise integrated current sensing in the industry. This precision will assist developers in achieving optimal performance without requiring an external shunt resistor.
The low-power GaN items from Texas Instruments can lower power losses by up to 94%. This will make the new charging solutions with less than a 75-watt rating rise to 94% efficiency. On the other hand, the chargers with more than a 75-watt rating can reach above 95% efficiency with the new FETs. (Anker GaN II 100W curr. US$ 59.99 on Amazon
What’s more intriguing is that the charging solutions with the new low-power GaN FETs can help reduce the size by as much as 50% when compared to normal silicon-based solutions.
The new product portfolio from Texas Instruments is optimized for the most common AC/DC power conversion geographies. You can find more about the new low-power GaN FETs on the official TI website
