Simply Wall St · 2d ago
  • Earlier this week, Power Integrations announced ultra-slim 15 W and 35 W auxiliary power supply reference designs tailored to NVIDIA’s Kyber 800 VDC AI data center architecture, using its InnoMux-2 ICs to cut board space and bill of materials by about 30 percent while maintaining at least 88 percent efficiency.
