As the performance of mobile phones, tablets, and other portable devices steadily increases, lightweight and compact power adapters for fast charging become an essential requirement. The ideal charger features comprise small volume and weight, high efficiency, large power for quick multi-device charging. GaN power devices are the best choice to achieve these requirements as they combine high efficiency and high power density.
Compared to traditional silicon-based power semiconductor devices, GaN devices present much lower resistance for the same voltage rating, thus reducing losses and heat generation. Moreover, lower output charge of GaN HEMTs allows for higher switching frequencies, thereby significantly reducing size and price of passive components. As a result, GaN-based fast chargers present higher efficiency, smaller footprint, and considerably increased power density, making this technology extremely promising for the consumer market.
Typical topologies that highly benefit from the superior properties of our smart GaN Devices are Totem Pole Power Factor Correctors, LLC DC-DC converters, and Flyback architectures. Here at NovaWave, we are constantly working to provide you with the best-in-class GaN devices to achieve more efficient, smaller, and cheaper fast-charger systems.
