The trend towards ever-larger data centres with much higher energy consumption, is driving a requirement for new power devices. One of the critical components in the distributed power architectures of data centres are the DC/DC (buck) converters to supply the point-of-load (PoL).
To meet these demands, the Berlin-based Ferdinand-Braun-Institut (FBH) has developed a novel, highly efficient and compact GaN-based buck converter operating in the very high frequency (VHF) range up to 200 MHz, which it first discussed in a paper last year at the 54th European Microwave Conference (EuMC) in Paris.
