| Summary: |
Vicor announces the introduction of a high power (>1100 W/in3) 320 W PRM™ non-isolated regulator. Designated P045F048T32AL, this latest V•I Chip component is designed for high-performance 48V power applications such as servers, telecom and ATE. This PRM provides a controlled Factorized Bus distribution voltage for powering downstream VTM™ current multipliers, creating fast, efficient, isolated, low-noise Point-of-Load (POL) converters. With an efficiency of 97% and matched with a 94% VTM unit, it enables direct 48 V-to-load with 91% efficiency, eliminating the need for an intermediate 12 V bus conversion stage and VRMs.

In combination, PRMs and VTMs form a complete DC-DC converter subsystem offering all of the unique benefits of Vicor´s Factorized Power Architecture (FPA)™: high density and efficiency, low-noise operation, architectural flexibility, extremely fast transient response, and elimination of bulk capacitance at the point of load. A PRM+VTM chip set provides up to 100 A or 300 W for a 48 V-direct-to-load density of over 500 W/in3. Alternatively, the PRM regulator may be used independently if isolation is not required.
The P045F048T32AL features unique Adaptive Loop compensation feedback. This single-wire alternative to traditional remote sensing and feedback loops enables precise control of an isolated POL voltage without the need for either a direct connection to the load or for noise-sensitive, bandwidth-limiting, isolation devices in the feedback path.
A 320 W PRM+VTM chip set to convert from 48 V direct to 1 V is available immediately from stock for $53 in OEM quantities (FOB Andover, USA).
Vicor´s comprehensive line of power solutions includes modular, high-density AC-DC and DC-DC modules and accessory components, fully configurable
AC-DC and DC-DC power supplies, and complete custom power systems.
