Vicor has introduced the MIL-COTS VI Brick Filter, which is available as a standalone filter or integrated with the PRM Regulator Module for military ground vehicle and airborne systems applications.

The integrated filter is an efficient (95 per cent) non-isolated regulator capable of boosting and bucking a 16.5-50V DC imput voltage and delivers output power up to 120W.

It provides compliance to MIL-STD-1275A/B/D and MIL-STD-704A-F for transients and MIL-STD-461E/F for EMI.

The standalone 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 16.5-50V DC and delivers output power up to 120W.

Measuring 48.6 x 27.7 x 9.5mm, this integrated package provides design flexibility and meets stringent EMI and transient protection specifications.

The MIL-COTS VI Brick Filter is designed to provide a controlled factorised 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 benefits of Vicor’s factorised 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).

Examples of ground vehicle applications include communication, targeting systems, flat panel displays, RF jamming and GPS mobile tracking.
