As cloud service providers and enterprise data centers scale their global footprints, efficient, reliable power delivery has become a critical enabler of performance, availability, and total cost of ownership. onsemi plays a key role in this evolving ecosystem, delivering advanced power, sensing, and control technologies that support the full power conversion chain—from grid‑connected front ends to high‑density point‑of‑load architectures. With deep expertise in high‑voltage, high‑efficiency, and high‑reliability solutions, onsemi helps cloud and data center designers meet increasing demands for power density, energy efficiency, and scalability. Industry forecasts point to strong, sustained growth across cloud and data center power systems, with the power supply market expanding at over 30% CAGR through the end of the decade. This growth is fueled by hyperscale and colocation deployments, high‑performance computing (HPC), AI training and inference, and the continued electrification of digital services worldwide—driving greater reliance on robust, efficient semiconductor solutions at every level of the data center power architecture.

AI data centers are hyperscale facilities built to support the extreme computational demands of GPUs, ASICs, and large language models (LLMs). Unlike traditional data centers, AI servers consume nearly 10× more power, with rack densities climbing from 30–120 kW today toward 1 MW per rack in the near future. This drives the need for higher-efficiency PSUs, wide-bandgap semiconductors (SiC and GaN) , and advanced thermal management. Why are AI data centers moving from 48V to 400V / 800V HVDC power architectures? The shift to ±400V and 800V HVDC (High Voltage Direct Current) architecture reduces conversion stages, lowers I²R losses, cuts copper usage by ~10×, and improves end-to-end efficiency to 94–96%. As AI racks push past 100 kW, 48V distribution becomes impractical due to massive currents (2.5–20 kA), making HVDC the new standard for OCP ORV3 and Diablo 400 deployments. What are the main power conversion stages in an AI server — from grid to GPU? A typical AI data center power chain includes: Utility Grid → Solid-State Transformer (or UPS) → AC-DC PSU (PFC + LLC) → Intermediate Bus Converter (IBC) → Multiphase DC-DC → Point-of-Load (PoL) regulators feeding CPUs, GPUs, ASICs, and FPGAs. Each stage requires specific components — PFC controllers , SiC / GaN MOSFETs , gate drivers , smart power stages , eFuses, and PoL buck regulators — all available from onsemi on DigiKey . When should I choose SiC MOSFETs, SiC JFETs, or GaN for AI data center power designs? Each wide-bandgap technology serves a different role: GaN with Integrated Driver (650V iGaN) : Best for high-frequency, high-density designs that need fast switching and compact form factor onsemi offers a complete WBG portfolio — SiC MOSFETs, Cascode JFETs, Combo JFETs, and integrated GaN (iGaN) — covering the full AI power stack. What efficiency targets and certifications should an AI data center PSU meet? PSUs must meet 80 Plus Titanium and OCP Open Rack V3 (ORV3) specifications, typically achieving ≥97.5% peak efficiency at 50% load with 20 ms hold-up time at full load. onsemi's 12 kW AI Cloud PSU reference design hits 98% peak efficiency using 650V M3S SiC MOSFETs combined with PowerTrench T10 MOSFETs — delivering 50% more power than typical competitors. Why does even a 0.5–1% efficiency improvement matter in AI data centers? In hyperscale deployments, a >0.5% efficiency gain saves ~165 GWh annually — equivalent to ~$19M in electricity costs across 3 million servers. Choosing higher-efficiency power components like onsemi SiC MOSFETs , PowerTrench T10 , and smart power stages directly reduces total cost of ownership (TCO), cooling load, and carbon footprint. What are the best AC-DC topologies for AI data center power supplies? The most common topologies are: Totem Pole PFC — highest efficiency, lowest THD (requires WBG devices like SiC or GaN) Vienna Rectifier — best for 3-phase, 25–30 kW HVDC PSU front-ends Full-Bridge LLC & Dual Active Bridge (DAB) — for isolated DC-DC stages Hybrid Switched Capacitor Converter (HSCC) — for high-density 48V-to-PoL conversion onsemi controllers like the NCP1681 (totem-pole PFC), NCP4390 (LLC), and FAN9673 (3-phase PFC) are commonly used for these designs. How do eFuses, hot-swap controllers, and solid-state circuit breakers protect AI servers? AI servers require fast, intelligent protection against overcurrent, inrush surges, short circuits, and overvoltage events. Smart fuses like the onsemi NCP81428 (50A hot-swap eFuse with PMBus) provide telemetry, peak current monitoring, and programmable protection. For 400V/800V HVDC architectures, SiC Combo JFETs and SiC JFETs enable solid-state circuit breakers (SSCBs) with lower losses, faster fault response, and higher efficiency than silicon-based alternatives. What multiphase controllers and smart power stages (SPS) are recommended for GPU and CPU power rails? GPU, CPU, ASIC, and FPGA power rails require multiphase buck regulation with precise transient response and high current density. onsemi's FD5012 (12-phase digital controller with PMBus) and FDMF5048 Smart Power Stage (up to 110 A peak) deliver >0.5% efficiency improvement over competing solutions — saving AI operators >$80M in electricity costs over their lifetime. For high-current PoL applications, the NCP3286 / NCP3296 stackable buck regulators support up to 160 A. What design tools, reference designs, and evaluation boards are available to accelerate AI power supply development? Engineers can speed up time-to-market using onsemi's free tools available alongside DigiKey component sourcing: Interactive Block Diagrams — for AI Data Center, AI Accelerated Server, Server PSU, and Server Motherboard Reference Designs — including the 12 kW AI Cloud PSU and 3 kW Totem-Pole PFC Evaluation boards like the NCP81428GEVB (hot-swap), NIV3071MTW4GEVB (4-channel eFuse), and NCP-NCV51563D2PAK7LGEVB (gate driver) are ready to order on DigiKey.
