Vicor Corp. has just introduced its PFM VI BRICK module, an isolated AC-DC converter with power factor correction. With its Adaptive Cell architecture empowering consistently high efficiency over various global AC mains, the PFM VI BRICK gives 330W at 48V (SELV) in a 9.5mm-thin profile.

Vicor reports that in contrast to low frequency AC-DC front ends using a PFC boost stage and a DC-DC down converter, the PFM VI BRICK module offers isolation, voltage transformation and PFC regulation in a single stage. The device accomplishes this with its high-frequency soft switching technology.

This initial PFM module complements an expanding array of VI BRICK and V.I Chip converter building blocks which provide unparalleled density, efficiency and connectivity from the wall plug to the point of load. The PFM module is Vicor's new flagship in its vision of a far-reaching power component methodology. Requirements for power systems operating from AC- or DC-input voltages across major electronic markets may be addressed more predictably and cost-effectively with modular components that support efficient power distribution and dense power conversion, necessitating flexibility and scalability.

The PFM module is now available in the thermally-adept, rugged VI BRICK package.
