Infineon Technologies AG announced that Chicony Power has selected its CoolGaN Transistors G5 to power multiple laptop adapters developed for a leading notebook manufacturer.
The design highlights how gallium nitride power semiconductors are enabling more compact and energy-efficient charging solutions. By using GaN technology, the new adapters can achieve smaller form factors while improving efficiency and sustainability for mainstream computing devices.
At the core of the adapter design are Infineon’s CoolGaN Transistors G5, optimized for fast switching and low conduction losses across a wide range of operating conditions. The devices are based on Infineon’s hybrid-drain gate injection transistor architecture, designed to deliver robust high-voltage gate operation, improved dynamic on-resistance performance, and higher saturation current to support reliable operation.
Compared with the previous generation, the G5 transistors deliver up to 30% improved performance in key figures of merit such as RDS(on) multiplied by gate charge. These improvements support higher efficiency and greater power density in compact adapter designs.
The adapter platform developed by Chicony Power incorporates high-frequency power architectures with optimized power factor correction and DC/DC conversion stages that leverage the fast switching capability of GaN devices. The design also includes EMI-optimized layouts and filtering to reduce electrical noise while maintaining strong compliance margins. Thermal optimization allows sustained power delivery in the 100 W to 300 W range while maintaining compact mechanical designs.
Infineon stated that it continues to expand its GaN portfolio, announcing more than 40 GaN products over the past year. The company is also progressing with scalable GaN manufacturing on 300-millimeter wafers, with initial samples already shipped to customers. According to Infineon, 300 mm GaN production will enable higher manufacturing capacity and faster delivery of GaN products as demand for high-efficiency power electronics grows.
