ROHM’s New EcoGaN™ Power Stage ICs BM3G0xxMUV-LB Series Contribute to Smaller Size and Lower Loss

PublishTime： 2023-09-02 Article Source：ROHM News

ROHM has developed Power Stage ICs with built-in 650V GaN HEMTs and gate drivers - the BM3G0xxMUV-LB series. The devices are ideal for primary power supplies inside industrial and consumer applications such as data servers and AC adapters.

Consumer and industrial sectors more and more demanded greater energy savings to achieve a sustainable society in the last few years. 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.

On top, the BM3G0xxMUV-LB series (BM3G015MUV-LB, BM3G007MUV-LB) incorporates additional functions and peripheral components designed to maximize GaN HEMT performance along with 650V GaN HEMTs - the next generation of power devices. ROHM’s features such as a wide drive voltage range (2.5V to 30V) enable compatibility with virtually any controller IC in primary power supplies - facilitating the replacement of existing silicon (Super Junction) MOSFETs. This makes it possible to simultaneously reduce component volume and power loss by approx. 99% and 55%, respectively, achieving higher efficiency in a smaller size.
