PRM Modules VI Chip

VI Chip® PRM™ Modules High Performance Buck-Boost Regulators ® S C US C NRTL US For use as a stand-alone high power buck-boost regulator or with a VTM™ for isolated factorized-power designs Description Features & Benefits PRM Modules enable power architects to maximize the density • Simple to use and performance of their high-power designs. The integration of a high-performance Zero-Voltage Switching (ZVS) topology nnPoint-of-load, ZVS Buck-Boost regulation with custom magnetics results in a fully integrated buck-boost nnFactorized Power Architecture regulator with over 97% efficiency. With wide input voltage nnMinimal external components ranges optimized for 24 and 48V inputs, these regulators provide a regulated 48V output which can be trimmed across a wide output • High density range. Full-sized packages (32.5 x 22 x 6.73mm) can convert up to nnUp to 2,040W/in3, with 600W/in 1.1in2 package 600W of power, also available in half-sized packages nnWide VIN optimized for 48VOUT (22 x 16.5 x 6.73mm) up to 250W. Higher-power conversion can be 45V , 38 – 55V range achieved by arraying modules together. IN IN 48VIN, 36 – 75VIN range Use of a ZVS topology enables high-frequency operation that maximizes efficiency by minimizing the significant switching losses • High efficiency associated with conventional buck regulators using hard-switching nnFull Chip: Up to 600W at 97.6% topologies. High switching frequency also reduces the size of the nnHalf Chip: Up to 250W at 96.7% external filter components, providing power density while enabling fast dynamic response to line and load transients. • Flexible MILCOTS version are also available.
