Vicor V•I Chip Power Converters


Direct, high efficiency 48V-to-1V, 130 A conversion at >89%


Vicor’s Factorized Power Architecture separates the regulation and voltage transformation functions of a power converter into two modules, the V•I Chip PRM™ regulator and the VTM™ current multiplier/voltage transformer. This provides greater functionality, density/efficiency, and design flexibility. These small, powerful modules make it easy to improve component and system performance. The modules reduce duplicated functions, have low distribution loss, and reduce power dissipation at the load. The flexibility of these functional modules also enables power system designers to develop unique power delivery systems that meet their specific application needs. Vicor's PRM/VTM Series Regulators
