Delivers 97.9% effectivity and 92.36 W/cm³ energy density to help 400 V DC architectures—perfect for AI, telecom, and industrial programs with tight house and thermal constraints.
Navitas Semiconductor, in collaboration with Nice Wall Energy, has launched a 2.5 kW DC-DC converter designed to fulfill the stringent energy density and effectivity calls for of recent AI-driven knowledge facilities. Housed in a compact quarter-brick type issue, this new module leverages Navitas’ superior GaNSense NV6169 energy IC to ship distinctive efficiency in space-constrained environments.
Supporting the shift towards 400 V DC cupboard architectures, the converter allows knowledge facilities to optimize house utilization and cut back vitality consumption. With an influence density of 92.36 W/cm³—as much as eight occasions higher than conventional silicon-based designs—operators can dedicate much less house to energy infrastructure and extra to compute {hardware}.
The important thing options are:
- Helps huge enter voltage vary: 320–420 VDC
- Achieves 97.9% effectivity at half-load
- Complies with Open Compute Venture requirements
- Supplies 0.2% effectivity acquire in high-frequency circuits
Central to the design is the NV6169 GaNSense energy IC, a 650 V, 45 mΩ GaN system that integrates driver, safety, and lossless present sensing right into a compact 8×8 mm PQFN bundle. Its built-in short-circuit safety prompts in simply 30 ns, considerably sooner than standard options. With an 800 V peak voltage ranking and ultra-low profile, the NV6169 enhances thermal efficiency and reduces design complexity, reaching effectivity acquire in high-frequency circuits.
Preferrred for AI servers, telecom tools, and industrial programs, this converter minimizes warmth technology and cooling calls for, simplifying system-level thermal design. Its small footprint and modular method help scalable energy supply in high-density rack configurations.
This new answer addresses the rising want for environment friendly, compact energy modules in knowledge facilities transitioning to 400 V DC programs. Past AI, the converter additionally advantages telecommunications and industrial purposes with strict house and vitality constraints.
