Innovative Low Resistance Power MOSFETs Enhance AI Server Efficiency
Introducing Advanced MOSFET Solutions for AI and Enterprise Servers
ROHM Semiconductor has unveiled a game-changing series of N-channel power MOSFETs that set new standards for low ON-resistance and broad Safe Operating Area (SOA) capabilities. This innovation comes at a time when demand for high-performance servers—especially those geared towards artificial intelligence (AI) and enterprise applications—is on the rise.
The Growing Demand for Efficient Servers
Recent advancements in data processing and the rapid pace of digital transformation have led to an increased need for enhanced data center servers. As companies integrate AI components with their infrastructures, the operational demands of these servers—running continuously—highlight the importance of energy efficiency. In particular, conduction losses linked to the ON-resistance of MOSFETs in power circuits can substantially compromise system performance. This is particularly relevant for AC-DC conversion circuits, where such losses can lead to marked energy inefficiency.
Challenges and ROHM's Innovative Solutions
To ensure the reliability of servers equipped with hot-swap functionalities that allow for component maintenance while powered, the need for wide SOA tolerance is essential. ROHM’s new DFN5060-8S package is designed to accommodate a larger die compared to traditional MOSFET designs, enabling these cutting-edge devices to achieve some of the lowest ON-resistances in the industry.
This evolution not only improves energy efficiency but also enhances the longevity and reliability of server power circuits. The new product lineup includes three specific models that meet these advanced requirements, allowing engineers to access specialized MOSFETs for varied applications.
The New Lineup of Low ON-Resistance MOSFETs
The lineup features:
- RS7E200BG (30V): Optimized for secondary-side AC-DC conversion circuits and hot-swap controller circuits in 12V power supplies used in high-performance enterprise servers.
- RS7N200BH (80V): Ideal for secondary AC-DC conversion circuits designed for 48V AI server power supplies.
- RS7N160BH (80V): Also targeted for secondary AC-DC conversion circuits in 48V systems.
All models utilize the DFN5060-8S package, which increases the die size by approximately 65% over the conventional HSOP8 package. This increase enables the RS7E200BG and RS7N200BH MOSFETs to achieve outstanding ON-resistance values of 0.53m? and 1.7m?, directly contributing to energy efficiency in server applications.
Enhanced Heat Dissipation for Improved Performance
Furthermore, ROHM has enhanced the internal clip design to maximize heat dissipation, which is critical for maintaining SOA tolerance. The RS7E200BG successfully exhibits an SOA tolerance exceeding 70A at a pulse width of 1ms and VDS = 12V, achieving performance that is significantly better than older MOSFET designs. This is essential for ensuring reliability in demanding server environments.
Future Outlook for ROHM’s Power MOSFETs
Looking ahead, ROHM plans to roll out mass production of these advanced power MOSFETs that are fully compatible with hot-swap controller circuits specifically for AI applications starting soon. This move is part of a broader strategy to expand ROHM's offerings, aiming to enhance energy efficiency and reliability across diverse applications that are crucial for modern technology infrastructures.
