The 2317 NBM is a bidirectional converter capable of delivering up to 750W continuously from 48V to 12V, or from 12V to 48V, with a maximum efficiency exceeding 98%. The NBM (NBM2317S54D1464T0R), capable of achieving a maximum power output of 1kW (up to 2ms), is integrated into a 23 x 17 x 7mm surface-mount package, providing a complete solution without the need for external circuitry. Switching at 2MHz, the NBM delivers low output impedance and fast transient response for dynamic loads. It also features hot-swapping and inrush current limiting, increasing system power density and saving valuable board space, time, and money.
In data centers still relying on 12V distributed power systems, the NBM supports advanced graphics processing units (GPUs) with 48V inputs using Power-on-Package (PoP) modular current multipliers (MCMs) from a 48V node that supplies a small fraction (1/48) of the GPU's current. This current multiplication overcomes the power supply limitations imposed by traditional 12V systems, which restrict bandwidth and connectivity. In data centers upgraded to a 48V infrastructure, the NBM can be used with existing 12V loads.
In hybrid and autonomous vehicles using 48V, the NBM is compatible with existing 12V subsystems for efficient 48V distributed power supply with or without two batteries.
