Linkcom Manufacturing Co., Ltd

LinkCom Manufacturing Co., Ltd. (stock code: 6821), a listed company with 36 years of experience in the field of magnetic components, today officially announced its latest technological breakthrough - High-Density Planar Transformer. This innovative technology significantly reduces transformer size, lowers DC resistance (DCR), and improves overall efficiency, bringing revolutionary changes to power supply design. Combining the optimization of magnetic components with the integration of peripheral power components, this technology is not only applicable to a variety of power topologies, but can also be customized to meet customer needs. It is expected to be widely used in high-growth markets such as server power supplies, automotive electronics and humanoid robots.
Compared with traditional products, the new flat transformer has achieved a major breakthrough in the design of magnetic components, reducing the volume by 20%, reducing the DC impedance by 20%, and improving the efficiency to the industry-leading level. By integrating power components and coupling capacitors, electromagnetic interference (EMI) in the power path is significantly reduced, while losses are reduced by 5%-10%. In addition, the core structure has been optimized to make the temperature distribution more uniform, improve the heat dissipation efficiency, and provide greater flexibility for customers' thermal management design.
This technology supports a variety of power topologies, including LLC, Phase-Shift Full-Bridge and HSC architectures, and can develop customized power transformer modules based on customer needs. The first batch of design prototypes use LLC architecture to achieve 48V to 12V step-down in a standard 1/8 brick size (58.4mm x 22.9mm), with power up to 1KW and peak efficiency of 97%, with room for further optimization in the future. The product manager of LinkCom said: "This transformer is not only a technological breakthrough, but also a direct response to market demand. Whether it is high-performance computing or automotive electronics applications, we can provide the best solution."
This technology upgrade is made possible by the collaboration between LinkCom and the industry’s top partners:
Power components: The operating frequency is increased to 1MHz, and combined with GaN FET from EPC, a third-generation semiconductor manufacturer, the switching efficiency and power density are significantly improved.
Control unit: Adopts Nuvoton's Arm Cortex-M7, which provides precise control and flexible design freedom while reducing the size of the control module.
Magnetic components: LinkCom introduced Maxwell magnetic field simulation software to assist in the design and verification of new magnetic materials and planar transformer structures, laying a foundation for high performance.
Market Outlook and Future Plans.
With the rapid growth of 5G, AI computing and electric vehicle markets, the demand for efficient and miniaturized power solutions is becoming increasingly urgent. Lianbao Electronics will continue to promote this technology into mass production, with the first batch of applications targeting data center power modules and step-down modules for automotive 48V systems. The company plans to continue optimizing its design, push efficiency to 98%, and expand to higher power applications to further consolidate its market leadership. The R&D Assistant Manager of LinkCom Electronics said: "For more than 30 years, we have focused on the innovation of magnetic components. The high energy density planar transformer we launched this time is the result of our technical strength and market insight. We are optimistic about the future of high-efficiency power supplies and look forward to working with global customers to promote this technology to a wider range of application scenarios."
