Vicor Introduces VI BRICK™
PRM Regulator and VTM Current Multiplier Modules

Powerbox is delighted to announce Vicor's introduction of the VI BRICKTM  PRM (Pre-Regulator Module) and VTM (Voltage Transformation Module) Current Multiplier, members of the new VI BRICK family that provides an advanced modular platform for power solutions. VI BRICK PRMsTM and VTMsTM  provide all of the technical advantages of Factorised Power extremely fast transient response, and elimination of bulk capacitance at the point of load.

VI BRICK PRMsTM and VTMsTM  offer a flexible and scalable architecture for DC-DC power conversion utilizing Factorized PowerTM in a robust “brick-like” package designed for efficient thermal management. The very flexible architecture facilitates several design configurations including multiple outputs, high power arrays, high-current/low voltage, and high voltage. These models include six PRMs, which perform the regulation function and twelve VTMs that take the “factorized bus voltage” from the PRM and provide transformation and isolation. 

The VI BRICKTM  PRM is a very efficient non-isolated regulator specifically designed to provide a controlled Factorized Bus distribution voltage for powering downsteam VI BRICKTM  VTMs. In combination, VI BRICKTM  PRMs and VTMs forma complete DC-DC converter subsystem offering the unique benefits of FPA including the capability of separating the regulation (PRM) and transformation (VTM) for improved board layout and thermal design.

The VI BRICKTM  VTM current multiplier delivers superior speed, power density, and efficiency to meet the demands of advanced power applications. A major benefit of the VI BRICKTM  VTM is that capacitance at the load can be nearly eliminated substantially increasing system density while improving reliability and decreasing cost. In applications requiring high current or redundancy, VI BRICKTM  VTMs can be operated in parallel without adding control circuity or signal lines.

VI BRICKTM  PRMs and VTMS provide unique advantages to designers due to the inherent flexibility they provide for architecture, layout, thermal management and design requirements.

VI BRICKTM  models are available in a base temperature grade of –40 to +100 oC, operating, and –40 to + 125 oC, storage, with a slotted-flange baseplate and through-hole pin style. All modules of the VI BRICKTM  family are RoHS compliant and compatible with lead-free wave soldering processes. These models are robust, thermally proficient, and compact with a footprint of 2.08 in2 and low profile of 0.37 inches (dimensions of 1.91 x 1.09 x 0.37 inch (48.6 x 27.7 x 9.5mm).
