Emerging computing applications demand more power in much smaller form factors. In addition to the expanding needs of the server market, some of the most challenging applications are multi-user gaming systems, autonomous cars, and artificial intelligence.

Additionally, automotive systems are moving from 12 V distribution systems to 48 V systems. This change is driven by the increase of power-hungry electronically-driven functions and the emergence of autonomous vehicles creating additional demands from systems such as lidar, radar, camera, and ultrasonic sensors upon the power distribution system.

These advanced applications are putting higher demands on the power converters, and silicon-based power conversion is not keeping pace.

The latest generation of 100 V GaN devices increase the efficiency, shrink the size, and reduce system cost for 48 V power conversion.

48 V = GaN: In all the topologies with 48 V_IN, the highest efficiency comes with using GaN devices.
