Offering advanced digital control, GaN and SiC power technologies, and up to 30% lower power losses—ideal for next-generation AI infrastructure.
Navitas Semiconductor has introduced a 12 kW power supply unit (PSU) tailored for the next wave of AI-driven hyperscale data centers. Designed to meet Open Rack v3 (ORv3) and Open Compute Project (OCP) standards, this high-efficiency PSU is purpose-built for dense server environments pushing up to 120 kW per rack.
The PSY consist of latest GaNSafe ICs and third-generation Fast SiC MOSFETs. Together, they power a 3-phase interleaved totem-pole PFC (TP-PFC) and full-bridge LLC (FB-LLC) architecture, achieving high performance while minimizing component count. The system is further enhanced by the proprietary IntelliWeave digital control platform, which seamlessly switches between CrCM and CCM modes for optimal efficiency across load conditions—delivering up to 30% lower power losses compared to conventional CCM solutions.
The key features include:
- Dimensions: 790 x 73.5 x 40 mm
- Input Range: 180 – 305 VAC
- Output: Up to 50 VDC, 12 kW (≥207 VAC input), 10 kW (below 207 VAC)
- Protections: Active current sharing, over-current, over-voltage, under-voltage, and thermal protection
- Cooling: Internal fan
- Operating Temp: -5 to 45°C
- Hold-up Time: ≥20 ms at full load
- Inrush Current: ≤3x steady-state current (under 20 ms)
The ICs used in this PSU integrate critical safety and performance features including fast short-circuit protection (350 ns response), ESD protection, and programmable slew-rate control—all packaged in a simple 4-pin configuration.
“This milestone marks a fourfold leap in power output over just two years,” said Gene Sheridan, Navitas CEO and co-founder. “With the explosion in GPU demand for AI workloads, our production-ready PSU provides a fast, scalable, and efficient solution for data center power delivery.”
