Vicor 2317 12 to 48 V NBM module

Wednesday, 04 April, 2018 | Supplied by: Vicor Corporation

Vicor has announced a non-isolated upconverter to support 48 V high-performance GPUs in data centres that are still relying on legacy 12 V power distribution.

The 2317 NBM converts 12 to 48 V with over 98% peak efficiency, 750 W continuous and 1 kW peak power in a 23 x 17 x 7.4 mm surface-mount SM-ChiP package. The product 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 MHz fast transient response to dynamic loads. It incorporates hot-swap and inrush current limiting.

The NBM supports 48 V input GPUs using Power-on-Package (PoP) modular current multipliers (MCMs) driven from a 48 V node sourcing a small fraction (1/48) 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.

Vicor Power-on-Package modules build on Factorized Power Architecture (FPA) systems deployed in high-performance computers and large-scale data centres. FPA provides efficient power distribution and direct conversion from 48 to 1 V for GPUs, CPUs and ASICs demanding up to 1000 A. By deploying current multiplication in close proximity to high current artificial intelligence (AI) processors, PoP MCMs enable high performance and system efficiency.
