VICOR NBM2317S60D1580T0R

The NBM2317S60D1580T0R 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. The NBM2317S60D1580T0R 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.
