48 V = GaN

More Efficient • Smaller • Lower Cost

Advanced computing applications for cloud computing, artificial intelligence, machine learning, and multi-user gaming are putting higher demands on the power converters, and silicon-based power conversion is not keeping pace. GaN devices increase the efficiency, shrink the size, and reduce system cost for 48 V power conversion.
