For modern switch-mode power supplies (SMPS) and battery-powered applications there is a clear trend towards higher efficiency and improved reliability. Supporting this trend, Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) introduces the OptiMOS™ 6 100 V with a new power MOSFET technology. The new technology is specifically optimized for high switching frequency applications such as telecom and solar, where losses are associated with charges (switching) and on-state resistance (conduction). At the same time, due to the best-in-class R DS(on) and wider safe operating area (SOA), it is also ideal for battery-powered applications (BPA) and battery management systems (BMS).
Taking advantage of a novel design concept, the OptiMOS 6 100 V family of MOSFETs comes with improved R DS(on) and industry’s best figures-of-merit (FOMs). It combines the benefits of exceptionally low on-state resistance and superior switching performances. The unique features of OptiMOS 6 allow for easier thermal design and less paralleling, leading to excellent efficiency, improved power density, system cost reduction, and prolonged lifetime.
Especially in the telecom market, OptiMOS 6 is a “game-changer” by achieving 18 percent lower R DS(on) and more than 30 percent improvement in FOMs (R DS(on) x Q g and Q gd), compared to the state-of-the-art OptiMOS 5 . In a 600 W, -(36-60) V to 12 V ZVS buck-boost converter, the OptiMOS 6 in SuperSO8 package with 2.2 mΩ can achieve one percent higher efficiency than OptiMOS 5 BSC027N10NS5 (2.7 mΩ) across the whole load range. This results in a 7 W lower power loss due to improved charges and R DS(on), enabling up to 15 percent higher power density. Among the key benefits, the new technology in the 100 V range allows for lower conduction and switching losses and minimizes the necessity for paralleling parts.
OptiMOS 6 100 V is now available in SuperSO8 5×6 and PQFN 3.3×3.3 packages in a broad range of R DS(on) classes from industry best-in-class to price/performance optimized. More information is available at http://www.infineon.com/optimos-6-100V.
