Reference link from GaN Systems: The Need for Multiple Approaches to GaN Circuit DesignPlay Video
GaN is one of the most important representatives of the third-generation semiconductor materials. GaN is a wide band gap material with advantages of high breakdown voltage, high current density, low conduction resistance, high efficiency of power conversion, and great thermal stability at high temperatures. From media reports and market predictions, GaN power device is entering a rapid growth era owing to the high market demands from automotive, industrial, and telecom applications.
The remarkable revenue increase of GaN power electronics is primarily attributed to the release of GaN-based fast chargers from smartphone manufacturers. These chargers enjoy excellent market acceptance due to their effective heat dissipation and small footprints. Notebook and computer manufacturers are showing great interest in adopting the fast charging technology in their notebook chargers as well. Going forward, more smartphone and notebook chargers are expected to feature GaN power electronics, which will lead to an expected year-over-year (YOY) revenue growth of 73% for GaN power devices in 2021 from Trendforce research report. It is estimated that by 2025, the market size of GaN power devices will reach $850 million, with a compound growth rate of 78% from 2020 to 2025.The GaN-based fast charging solution can also apply to other electronic products, such as electric bicycles and electric vehicles.
Cost efficiency and environmental friendliness are core elements in modern lighting solutions. LED lighting has gained tremendous attention and popularity over the years as it has been proven to be energy-saving with excellent illumination effects.
