Vicor's MIL-COTS VI BRICK Filter

Vicor has announced the introduction of the MIL-COTS VI BRICK Filter, available as a stand-alone filter or integrated with the PRM Regulator Module.

The integrated filter is an efficient (~95%) non-isolated regulator capable of both boosting and bucking a wide-range input voltage (16.5 – 50 VDC) and delivers output power up to 120 W. Smaller than comparable competitive products, it provides compliance to MIL-STD-1275A/B/D and MIL-STD-704A-F for transients and MIL-STD-461E/F for EMI.

The stand-alone MIL-COTS VI Brick Filter is a separate DC front-end module that provides EMI filtering and transient protection. The filter enables designers using Vicor’s MIL-COTS VI BRICK and V·I Chip PRMs to meet conducted emission / conducted susceptibility per MIL-STD-461E/F and input transients per MIL-STD-704A/E/F and MIL-STD-1275A/B/D. It accepts an input voltage of 16.5 – 50 VDC and delivers output power up to 120 W.

Substantially smaller than competitive products with similar power ratings – 48.6 x 27.7 x 9.5 mm (1.91 x 1.09 x 0.37 in) - this integrated package provides design flexibility and meets stringent EMI and transient protection specifications.

The MIL-COTS VI BRICK Filter is specifically designed to provide a controlled Factorized Bus distribution voltage for powering downstream VI BRICK VTM current multipliers that are fast, efficient, isolated, low-noise point-of-load (POL) converters. In combination, VI BRICK PRMs and VTMs form a complete DC-DC converter subsystem offering all of the unique benefits of Vicor’s Factorized Power Architecture (FPA). The benefits include: high density and efficiency, low-noise operation, architectural flexibility, extremely fast transient response, and elimination of bulk capacitance at the point-of-load (POL).
