Vicor Corp. 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 – 50Vdc) and delivers output power up to 120W. Said by the company to be smaller than comparable competitive products at 2.19 x 1.91 x 0.37 inches (55,7 x 48,6 x 9,5mm), 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 VI 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 – 50Vdc and delivers output power up to 120W.
"Substantially smaller than competitive products with similar power ratings, this integrated package provides design flexibility," said Kai Johnstad, Sr. Product Marketing Manager, "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 V™™ current multipliers that are fast, efficient, isolated, low-noise point-of-load (POL) converters. In combination, VI BRICK PRMs and V™s 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).
Applications for the new VI BRICK Filter are typically military ground vehicle and airborne systems. Examples of ground vehicle applications include communication, targeting systems, flat panel displays, RF jamming, and GPS mobile tracking.
Standard lead time for the MIL-COTS VI BRICK Filter is from stock to four weeks. North American pricing for the VI BRICK PRM with Integrated Filter is as low as $157 USD in OEM quantities; the stand-alone filter is as low as $67 USD, also in OEM quantities.
