ANDOVER, Mass., 2 Feb. 2007. Vicor Corp. has introduced a high power 320-Watt PRM non-isolated regulator.
Designated P045F048T32AL, this VI Chip component is designed for high-performance 48-volt power applications such as servers, telecom, and ATE. The device produces 1,100 Watts per square inch.
This PRM provides a controlled factorized bus distribution voltage for powering downstream VTM current multipliers. With an efficiency of 97 percent and matched with a 94 percent VTM unit, it enables direct 48-volt-to-load with 91 percent efficiency, eliminating the need for an intermediate 12-volt bus conversion stage and VRMs.
The P045F048T32AL features 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.
