48V to 12V Converter for Data Center and Automotive Power Applications

The NBM2317

Efficiently Bridging 12V to 48V Computing Solutions Automotive Solutions

800W continuous, 1kW peak power

The NBM provides bidirectional 48V to 12V conversion with 97.9% peak efficiency at 800W continuous and 1kW peak power in a package less than 3.3cm³. Switching at 1.7MHz, the NBM takes up a fraction of the space consumed by slow switching (sub 1MHz) solutions requiring a large multiplicity of discrete components. The NBM responds to transient loads quickly (1 microsecond) while maintaining its output within a narrow voltage band. A complete power solution, the NBM delivers voltage essentially free of noise without requiring external filters, bulk caps, hot swap or in-rush current limiting.

Benefits of the NBM

97.9% peak efficiency

Less space than discrete designs

Fast transient response for multiple loads

Parallel capable for higher power

Data center solutions for 48V and 12V infrastructures

Artificial Intelligence is driving rapid change in data centers and high-performance computing. Increased processor speeds are required to support AI machine learning, driving commensurate increases in the power required by XPUs. While state-of-the-art GPU-enabled computing systems use 48V for increased power capability and total system efficiency, many systems still rely on legacy 12V infrastructure and 12V loads. The NBM enables migration from 12V to 48V systems.

Bridging automotive 48V Power Delivery Networks (PDNs) to 12V loads

Automobiles are adding 48V batteries to meet increasing powertrain performance and new safety feature demands while reducing CO₂ emissions. In order to reduce the size, weight and cost of a vehicle's power harness, PDNs within electric and hybrid vehicles are migrating from 12V to 48V requiring an easy to use, power-dense and efficient converter to bridge the 48V to multiple 12V loads.
