Infineon Technologies Launches Improved Power MOSFET Tech

For modern switch-mode power supplies (SMPS) and battery-powered applications, there is an emerging trend towards higher efficiency and improved reliability. Supporting this trend, semiconductor manufacturing company Infineon Technologies is introducing the OptiMOSTM 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 RDS(on) and wider safe operating area (SOA), it is also ideal for battery-powered applications (BPA) and battery management systems (BMS),” claims the company.

The OptiMOS 6 allows for easier thermal design and less paralleling, leading to increased efficiency, improved power density, reduced system cost, and prolonged lifetime.

“Especially in the telecom market, OptiMOS 6 is a game-changer by achieving 18 percent lower RDS(on) and more than 30 percent improvement in FOMs (RDS(on) x Qg and Qgd), 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,” claims Infineon Technologies.

This, as per the firm, results in a 7 W lower power loss due to improved charges and RDS(on), enabling up to 15 percent higher power density. The new technology in the 100 V range is said to allow for lower conduction and switching losses and minimizes the necessity for paralleling parts.

In the framework of telecom power system, by switching to the new MOSFET technology, the annual electricity saving potential equals the electricity consumption of 170 households, states Infineon Technologies. The devices help to reduce the energy consumption by one million Euros over a time span of ten years, it adds.
