Power Integrations (NASDAQ:POWI), the leader in high-voltage integrated circuits for energy-efficient power conversion, today introduced two new ultra-slim, compact auxiliary power supply reference designs for 800 VDC AI data centers. The single-output, 15 W design is only 30 mm by 30 mm with a 7 mm profile, while the isolated, six-rail, 35 W design is only 80 mm by 60 mm with an 8 mm profile. Optimized specifically for the NVIDIA Kyber liquid-cooled, blade-rack architecture, these ultra-compact solutions free up approximately 30 percent space on densely packed main power distribution boards (PDBs) with an estimated 30 percent reduction in the BOM count—streamlining design and improving overall reliability. These designs are highly efficient with at least 88 percent efficiency across line and load.
