Power regulator module

  • 26-Jul-2010 01:54 EDT

The V.I. Chip half-chip power regulator module (PRM) from Vicor provides a power-dense solution for applications with limited space. The 16.5 x 22 x 6.7 mm package features 97% efficiency at 200 W with the same power density as a 400-W full-size PRM. The device operates from 48 V dc (38 to 55 V) to generate a regulated, adjustable 5 to 55 V output. The ZVS Buck – Boost topology and high-switching-frequency (~1 MHz) operation enable high efficiency and reduced size to reach a power density of over 1300 W/in3. The half-chip PRM can be used as a stand-alone, nonisolated voltage regulator or combined with full-chip or half-chip voltage-transformation-module current multipliers.
