VICOR NBM2317S60D1565T0R NBM™ Non-isolated Bus Converter Module

NBM2317S60D1565T0R is a high-efficiency Non-Isolated Bus Converter operating from a 40 to 60VDC high-side voltage bus to deliver a ratiometric low-side voltage from 10 to 15VDC.

NBM2317S60D1565T0R offers low noise, fast transient response, and industry-leading efficiency and power density. In addition, it provides an AC impedance beyond the bandwidth of most downstream regulators, allowing input capacitance normally located at the input of a PoL regulator to be located at the high side of the NBM. With a high-side to low-side K factor of 1/4, that capacitance value can be reduced by a factor of 16x, resulting in savings of board area, material and total system cost.

Leveraging the thermal and density benefits of Vicor SM-ChiP packaging technology, the NBM offers flexible thermal management options with very low top- and bottom-side thermal impedances. Thermally-adept SM-ChiP-based power components enable customers to achieve low-cost power system solutions with previously unattainable system size, weight and efficiency attributes quickly and predictably.

The NBM non-isolated topology allows bidirectional start up and steady-state operation and provides bidirectional fault detection and shut down.
