Compact AC adapter with ROHM’s EcoGaN power IC adopted in MSI’s products
ROHM has announced that its EcoGaN power stage IC has been adopted in the AC adapter for MSI’s products, including gaming laptops.
The AC adapter, developed by Delta Electronics, integrates ROHM’s EcoGaN power stage IC “BM3G005MUV-LB,” which features high-speed switching operation and low ON resistance. Combined with Delta’s power supply design expertise and energy-efficient power management technologies, this collaboration enables substantial size reduction and energy savings compared to conventional adapters.
Thanks to the integration of the EcoGaN power stage IC, the AC adapters Delta designed for MSI products can deliver high power output and maintain peak output for a certain period of time. This ensures stable power delivery even under high-load conditions typical of gaming environments requiring high performance.
As gaming laptops continue to evolve with increasingly powerful GPUs and CPUs, their power consumption has also risen. This trend demands AC adapters capable of delivering high power while meeting user expectations for portability through miniaturisation.
GaN devices, known for their low ON resistance and high-speed switching characteristics, are gaining attention for their ability to improve power supply efficiency and reduce the size of peripheral components such as inductors. ROHM’s power stage IC integrates a 650V GaN HEMT, gate driver, protection features, and peripheral components into a single package, enabling maximisation of GaN HEMT performance just by replacing conventional silicon MOSFETs.
ROHM’s GaN HEMT Power Stage ICs provide a solution for electronics systems that requires high power density and efficiency. A GaN HEMT and a gate drive driver optimised to maximize the performance of the GaN HEMT are included in one package. With wide input voltage range 2.5V to 30V, it can be combined with any controller IC. This IC is designed to adapt major exist controllers, so that it also can be used to replace the traditional discrete power switches, such as Super Junction MOSFET.
