ROHM's Unleashes 650V GaN Power Stage IC Masterpiece

ROHM proudly introduces the BM3G0xxMUV-LB series, a cutting-edge power stage IC incorporating both 650V GaN HEMT and gate driver integration. These components represent a formidable solution for a wide spectrum of applications, including industrial setups and consumer devices like data servers and AC adapters, where they serve as the primary power source.

In recent years, there has been a growing emphasis on energy conservation in both consumer and industrial sectors, as part of a broader commitment to sustainable development. GaN HEMT technology holds significant potential for driving miniaturization and enhancing power conversion efficiency. However, it has historically posed challenges in terms of gate driver complexity, necessitating the use of dedicated gate drivers.

ROHM has risen to this challenge by developing a sophisticated power stage IC, drawing on core power and analog technologies to seamlessly integrate GaN HEMT and gate drivers into a single compact package. This breakthrough simplifies the design and installation process, providing a streamlined solution for engineers and designers.

Additionally, the BM3G0xxMUV-LB series, which includes models like BM3G015MUV-LB and BM3G007MUV-LB, incorporates an array of advanced features and peripheral components, meticulously designed to optimize GaN HEMT performance and the next-generation 650V GaN HEMT power devices. Notably, ROHM's power stage IC offers a wide drive voltage range (ranging from 2.5V to 30V), making it compatible with nearly all controller ICs found in primary power supply systems. This compatibility allows for the seamless replacement of existing silicon (super-junction) MOSFETs. The result is a remarkable 55% reduction in component volume and power losses, leading to enhanced efficiency within a more compact form factor.

Isaac Lin, the General Manager of Delta Electronics' Power Semiconductor Application Development Center (PSADC), emphasizes the significance of GaN devices, stating, "GaN devices have garnered substantial industry attention due to their pivotal role in advancing equipment miniaturization and improving energy efficiency."

ROHM's innovative products harness the power of its proprietary analog technology to ensure high-speed, secure gate driving. This advancement is set to further catalyze the adoption and utilization of GaN power devices in a diverse range of applications.
