ROHM Co., Ltd. has announced that its EcoGaN™ power stage IC has been adopted in the AC adapter developed by Delta Electronics for MSI’s high-performance products, including gaming laptops. The collaboration brings together ROHM’s advanced GaN technology and Delta’s expertise in power supply design to deliver compact, energy-efficient power adapters tailored for demanding computing environments.

The AC adapter features ROHM’s BM3G005MUV-LB, a high-speed switching power stage IC with low ON resistance. Integrated into Delta’s latest adapter design, this solution achieves significant size reduction and energy savings compared to traditional silicon-based adapters, while maintaining high power output and performance stability under heavy loads—an essential requirement for gaming laptops equipped with powerful GPUs and CPUs.

As power demands rise in gaming and edge computing devices, GaN technology is gaining prominence due to its ability to improve efficiency and reduce system size. ROHM’s EcoGaN™ power stage IC integrates a 650V GaN HEMT, gate driver, protection circuitry, and peripheral components into a single compact package. This simplifies the design process and enables maximum GaN HEMT performance by directly replacing conventional silicon MOSFETs.

“The combination of Delta’s state-of-the-art power supply solutions and ROHM’s EcoGaN™ power stage IC has enabled high power delivery, optimal energy efficiency, and miniaturization in this AC adapter for gaming laptops,” said Red Lin, General Manager of the Edge Computing Power Business Unit at Delta Electronics, Inc. “We are proud that this solution has been adopted in MSI’s products, a globally recognized brand.”

Satoru Nate, Division Manager of the Power GaN Solution & Product Development Division at ROHM Co., Ltd., added, “Delta Electronics and ROHM have long collaborated in the field of power systems. This successful adoption reflects the strength of combining Delta’s design capabilities with ROHM’s device innovation. We aim to continue contributing to the miniaturization and efficiency of power systems across gaming, servers, industrial, and automotive applications.”

The integration of ROHM’s EcoGaN™ technology into consumer-grade power solutions marks a significant step in advancing the adoption of GaN devices in compact, high-efficiency applications.
