Non-isolated Up Converters Support High-Performance GPUs

Vicor has announced a 12 V to 48 V non-isolated up converter to support 48 V high-performance GPUs in data centers that are still relying on legacy 12 V power distribution. The 2317 NBM converts 12 V to 48 V with over 98% peak efficiency, 750 W continuous and 1 kW peak power in a 23 mm x 17 mm x 7.4mm surface-mount SM-ChiP package. The NBM (NBM2317S14B5415T00) provides a complete solution with no external input filter or bulk capacitors required. By switching at 2 MHz with ZVS and ZCS, the NBM provides low output impedance and Megahertz-fast transient response to dynamic loads. The NBM incorporates hot-swap and inrush current limiting.

The NBM supports state-of-the-art 48 V input GPUs using Power-on-Package (“PoP”) Modular Current Multipliers (“MCMs”) driven from a 48 V node sourcing a small fraction (1/48th) of the GPU current. Current multiplication overcomes the power delivery boundaries imposed by traditional 12 V systems standing in the way of higher bandwidth and connectivity.

The Vicor Power-on-Package modules build upon Factorized Power Architecture (FPA) systems deployed in high-performance computers and large-scale data centers. FPA provides efficient power distribution and direct conversion from 48 V to 1 V for GPUs, CPUs and ASICs demanding up to 1,000 A. By deploying current multiplication in close proximity to high-current Artificial Intelligence (AI) processors, PoP MCMs enable higher performance and system efficiency.
