Vicor NBM2317 Bus Converter

Vicor’s NBM2317 Bus Converter is a non-isolated fixed ratio DC-DC converter to bridge 12V and 48V systems in automotive and data center applications among others. 

The bus converter is fully bidirectional and has a 4:1 conversion ratio, with a high side voltage of 38V to 60V and a low-side voltage of 9.5V to 15V. It has a maximum continuous output power of 800W and operates at 97.9% peak efficiency. The converter requires no external components and switches at 1.7MHz, enabling a much higher power density than discrete alternatives and providing a very fast response to transient loads.

The NBM2317 has built-in hot-swap capabilities, current limiting, and other protections, supporting parallel operation to meet larger load requirements.
