In summary, ROHM's power stage IC features a built-in 650 V GaN HEMT and gate driver. These devices are ideal for primary power supplies inside industrial and consumer applications such as data servers and AC adapters. Consumer and industrial sectors are demanding greater energy savings to achieve a sustainable society. However, while GaN HEMTs are expected to significantly contribute to greater miniaturization and improved power conversion efficiency, the difficulty in handling the gate compared to silicon MOSFETs requires the use of a dedicated gate driver. In response, ROHM developed power stage ICs that integrate GaN HEMTs and gate drivers into a single package by leveraging core power and analog technologies, facilitating mounting considerably.
