Magnachip Semiconductor Corporation has announced a significant expansion in the production of its 7th generation MXT LV MOSFETs, powered by the company’s advanced Super Short Channel FET (SSCFET) technology. This move aligns with the increasing demand for compact low-voltage MOSFETs with reduced RSS(on) resistance, which plays a key role in enhancing mobile device efficiency.
Cutting-Edge Technology for Enhanced Battery Performance
As smartphones and other mobile devices become more sophisticated, the need for components that ensure greater efficiency, lower power loss, and improved battery life has risen. Magnachip’s MXT LV MOSFET series addresses these requirements by offering extremely low RSS(on) values, made possible through the integration of SSCFET technology. This technology minimizes the channel length between the source and drain in the on-state, resulting in lower energy consumption, better battery performance, and reduced thermal output, which prevents overheating.
Innovative Packaging for Design Flexibility
The new MXT LV MOSFETs are manufactured using wafer-level chip scale packaging (WLCSP) with a thickness of just 100µm. This ultra-thin design offers manufacturers more flexibility when creating compact, high-performance mobile devices. These MOSFETs are ideal for various consumer electronics, including smartphones, smartwatches, wireless earbuds, and innovative ring-shaped devices.
Adoption in Premium Smartphones and High-Volume Models
Magnachip has strengthened its position in the mobile market by supplying its MXT LV MOSFETs to a leading global smartphone manufacturer. The MDWC0151ERH model, one of the flagship MOSFETs from this series, has been adopted for use in the brand’s premium smartphone line. Additionally, the MDWC12D025ERH is now incorporated into the company’s popular midrange smartphone models, demonstrating the versatility and scalability of these components.
During the first three quarters of 2024, the production of MXT LV MOSFETs saw a 120% increase compared to the same period in 2023, reflecting the growing market demand for energy-efficient semiconductor solutions.
CEO Remarks on Strategic Growth and Innovation
YJ Kim, CEO of Magnachip Semiconductor, emphasized the company’s commitment to ongoing innovation and collaboration. “Our close partnership with a major global smartphone manufacturer has allowed us to bring high-quality products to the market. We aim to further expand our MXT LV MOSFET portfolio and explore additional battery-powered markets, including e-bikes, scooters, e-cigarettes, and drones.”
