Core Viewpoint - The article discusses the significant impact of artificial intelligence (AI) on various sectors, particularly focusing on the increasing power consumption of AI servers and the need for efficient power solutions to address this challenge [2][4][10]. Group 1: AI Server Demand and Power Consumption - The demand for AI servers is surging, leading to a notable increase in power consumption, with projections indicating that by 2030, AI will consume approximately 1000 TWh, accounting for at least 10% of global electricity [4][10]. - The rise in power consumption presents challenges, especially for regions with limited energy supply, necessitating solutions to either increase power generation or reduce power consumption in AI servers [7][10]. Group 2: Solutions and Industry Response - The industry is focusing on developing low-energy solutions to mitigate the power consumption issue, with companies like NVIDIA leading the charge in creating more efficient chips and systems [7][12]. - High voltage systems, such as ±400V DC and 800V DC, are being promoted to reduce current and copper usage, which is essential for improving efficiency in AI server operations [10][12]. Group 3: Impact of Increased Power Consumption - Increased power consumption leads to several challenges, including: 1. Power loss due to resistance in cables, resulting in energy waste and heat generation [11]. 2. Physical limitations in handling high currents, leading to increased costs and space issues in data centers [11]. 3. The need for advanced cooling systems to manage heat generated from power consumption [11]. 4. Limits on scalability for existing architectures to support high power densities [11]. 5. Rising operational costs, with nearly 60% of data center operating costs attributed to electricity [11]. Group 4: Role of Rohm Semiconductor - Rohm Semiconductor is positioned to provide comprehensive solutions for AI servers, focusing on power electronics and analog technologies to support the growing demand for efficient power management [14][16]. - The company is developing a diverse range of products using silicon, silicon carbide (SiC), and gallium nitride (GaN) to address various power needs in AI applications [16][19]. - Rohm's advancements include the introduction of fifth-generation SiC products, which significantly reduce on-resistance and support low-loss operation under high-temperature and high-load conditions [19][24]. Group 5: Product Offerings and Innovations - Rohm offers a variety of power MOSFETs and other components designed for high voltage applications, such as the RY7P250BM and RS7P200BM, which are suitable for AI server power supplies [22][26]. - The company emphasizes the importance of high power efficiency and density in its product development to meet the evolving needs of AI server technology [24][26].
