Game Changer! Infineon Unveils Next-Gen CoolGaN Tech for Efficient Power Systems

These innovations are expected to improve the efficiency, density, and cost-effectiveness of power management systems in various applications.


Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) has introduced two groundbreaking technologies, CoolGaN™ Bidirectional Switch (BDS) and CoolGaN Smart Sense, aimed at enhancing the performance and cost-effectiveness of power systems.

CoolGaN Bidirectional Switch (BDS): This family offers improved switching behavior (both soft and hard switching) with versions available at different voltage ratings (40V, 650V, and 850V) [1]. Applications include USB ports in mobile devices, battery management systems, inverters, and rectifiers [1]. The higher voltage versions (650V and 850V) are particularly notable for their design with features like four operational modes and the ability to replace multiple conventional transistors with a single unit, leading to benefits in efficiency, size, reliability, and cost.

CoolGaN Smart Sense: This technology integrates current sensing functionality with a transistor switch, simplifying design and minimizing power loss. It’s ideal for consumer USB-C chargers and adapters.

These innovations are expected to improve the efficiency, density, and cost-effectiveness of power management systems in various applications.
