Detailed performance evaluation of silicon and GaN power FETs is presented for chip-scale DC/DC converter applications. It is shown that improved GaN power FETs and silicon MOS power diodes can potentially lead to nearly 90% power conversion efficiency when switched at 5 MHz in a synchronous buck converter topology.
