New NBM Supports 48V/12V Automotive and Data Center Applications

June 5, 2018

Today at the PCIM Europe show in Nürnberg, Germany, we announced a new Non-Isolated Bus Converter Module (NBM) that enables hybrid 48V/12V power systems in data center and automotive applications.

NBMs are bidirectional non-isolated fixed-ratio converters, and the new NBM2317 is capable of providing up to 750W continuously at 48V from 12V, or at 12V from 48V, with over 98% peak efficiency.

Many data centers still rely on legacy 12V distribution. This new NBM simplifies support of state-of-the-art 48V input GPUs in such systems. The NBM drives the Power-on-Package (PoP) Modular Current Multipliers (MCMs) at 48V, reducing losses as it needs only to source a small fraction (1/48) of the GPU current. In data centers that have been upgraded to a 48V infrastructure, the NBM can be used to support legacy 12V loads.

In mild hybrid and autonomous vehicles using 48V, the NBM supports legacy 12V subsystems from efficient power distribution at 48V.

The new NBM provides a complete solution with no external circuitry needed and delivers up to 1kW of peak power capability (for up to 2ms) in a 23 x 17 x 7mm surface-mount package, optimizing power density and simplify system design. The NBM incorporates hot-swap and inrush current limiting, increasing power system density and saving valuable board space, time and money.
