Building the Smallest and Most Efficient 48 V to 5 - 12 V DC to DC using eGaN FETs and ICs

The Power and Evolution of GaN – Part 2 of 6 part series

Building the Smallest and Most Efficient 48 V to 5 - 12 V DC to DC using eGaN FETs and ICs
With the power architecture transition from a 12 V to a 48 V bus power distribution in modern data centers, there is an increased demand to improve 48 V power conversion efficiency and power density. In this context, DC-DC converters designed using eGaN® FETs and ICs provide a high efficiency and high power density solution. Additionally, with the advent of 48 V power systems in mild-hybrid, hybrid and plug-in hybrid electric vehicles, GaN transistors can provide a reduction in size, weight, and Bill of Materials (BOM) cost.

GaN-Based VRM Hybrid Converter Achieves 95% Efficiency for 48V to 1-2V/10A Power Conversion

GaN-Based VRM Hybrid Converter Achieves 95% Efficiency for 48V to 1-2V/10A Power Conversion

With the emergence of the 48V bus architecture, a new hybrid converter using gallium nitride (GaN) transistors can be employed which achieves a peak efficiency that exceeds 95% and with 225W/in3 power density. Of great interest for data center applications, where light load efficiency is critical for energy savings, the converter efficiency is kept higher than 90% down to a 20% load.
