Power Integrations Unveils Space-Saving, Ultra-Slim Auxiliary PSU Reference Designs for NVIDIA Kyber 800 VDC AI Data Center<\/b><\/p>\n

\nCompact, low-profile designs use highly integrated, 1700 V-rated PowiGaN\u2122, single-HEMT ICs to save space, simplify designs, improve reliability and lower BOM count with 88 percent efficiency<\/p>\n

TAIPEI, Taiwan–(BUSINESS WIRE<\/a>)–COMPUTEX <\/b>\u2013Power Integrations<\/a> (NASDAQ: POWI<\/a>), 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\u2014streamlining design and improving overall reliability. These designs are highly efficient with at least 88 percent efficiency across line and load.<\/p>\n

\"Compact,<\/p>\n

Compact, low-profile designs using 1700 V-rated PowiGaN, single-HEMT ICs save space, boost efficiency, and improve reliability for NVIDIA Kyber 800 VDC AI Data Center.<\/p>\n<\/div>\n

\n\u201cAs the only company offering single-HEMT 1700 V GaN devices, Power Integrations can design these best-in-class, highly efficient flyback converters with a low BOM count while maintaining wide safety margins on an 800 V bus,\u201d said Jason Yan, Senior Training Manager at Power Integrations. \u201cThe only alternative solutions are discrete, costly silicon carbide (SiC) devices which require 30 percent more components and space to operate.\u201d<\/p>\n

\nThe newly published design example reports describe 35 W and 15 W flyback auxiliary power supplies for high-voltage AI data center applications. These compact power supply units (PSUs) provide power for internal components such as MCUs, gate drivers, and op-amps, which deliver critical \u201ccontrol and housekeeping\u201d functions to ensure reliability, efficiency and system safety.<\/p>\n

\nBoth designs are based on Power Integrations\u2019 InnoMux\u2122-2<\/a> ICs with 1700 V PowiGaN gallium-nitride (GaN) technology. The 1700 V-rated InnoMux-2 IC easily supports 1000 VDC nominal input voltage in a flyback configuration and can deliver flat efficiency of 90 percent in discontinuous conduction mode (DCM) while maximizing power delivery.<\/p>\n
