PRM48BF480T400A00 (Formerly VIP0001TFJ) PRM™ Regulator Features - - - - - - - 45 V (38 to 55), non-isolated ZVS buck-boost regulator 5 to 55 V adjustable output range Building block for high efficiency DC-DC systems 400W output power in 1.1 in2 footprint 97% typical efficiency, at full load 1,360 W/in3 (83 W/cm3) Power Density Enables a 48 V to 1.5 V, 230 A isolated, regulated solution with total footprint of 3.3 in2 (21 cm2) - Flexible “Remote Sense” architecture optimizes regulation / feedback loop design to fit application requirements - Current feedback signal allows dynamic adjustment of current limit setpoint - 3.61 MHrs MTBF (MIL-HDBK-217Plus Parts Count) DESCRIPTION The V- I Chip™ PRM™ Regulator is a high efficiency converter, operating from a 38 to 55 Vdc input to generate a regulated 5 to 55 Vdc output. The ZVS buck - boost topology enables high switching frequency (~1 MHz) operation with high conversion efficiency. High switching frequency reduces the size of reactive ponents enabling power density up to 1,360 W/in3. The full V- I Chip package is patible with standard pickand-place and surface mount assembly processes with a planar thermal interface area and superior thermal conductivity. In a Factorized Power Architecture™ system, the PRM48BF480T400A00 and downstream VTM™ current multiplier minimize distribution and conversion losses in a high power solution. An external control loop and current sensor maintain regulation and enable flexibility both in the design of voltage and current pensation loops to control of output voltages and currents.
