PRM Regulator Remote Sense Only PRM48Bx480y600A00 HighEfficiencyRemoteSensePRMConverter FEATURES DESCRIPTION The VI Chip PRM Regulator is a high efficiency 45V (38 to 55 V ), non-isolated ZVS buck-boost IN converter, operating from a 38 to 55 Vdc input to regulator generate a regulated 5 to 55 Vdc output. The ZVS Buck 5 to 55 V adjustable output range Boost topology enables high switching frequency (~1 Building block for high efficiency DC-DC systems 2 MHz) operation with high conversion efficiency. High 600W Output Power in 1.11 in footprint switching frequency reduces the size of reactive 97.6% typical efficiency, at full load 3 3 3 components enabling power density up to 2,072 W/in . 2,072 W/in (124 W/cm ) Power Density Enables a 48 V to 1.5 V, 345 A isolated, regulated 2 2 The full VI Chip package is compatible with standard solution with total footprint of 3.3in (21cm ) pick-and-place and surface mount assembly processes Flexible Remote Sense architecture optimizes with a planar thermal interface area and superior thermal regulation / feedback loop design to fit application conductivity. requirements Current Feedback signal allows dynamic adjustment In a Factorized Power Architecture system, the of current limit setpoint PRM48BF480T600A00 and downstream VTM 6.36 MHrs MTBF (MIL-HDBK-217Plus Parts Count) transformer minimize distribution and conversion losses in a high power solution. TYPICAL APPLICATIONS An external control loop and current sensor maintain High Efficiency Server Processor and Memory Power regulation and enable flexibility both in the design of High Density ATE system DC-DC power voltage and current compensation loops to control of Telecom NPU and ASIC core power output voltages and currents.

Operation at or beyond these maximum ratings can cause permanent damage to device. Electrical specifications do not apply when operating beyond rated operating conditions. All voltages are specified relative to SG unless otherwise noted. Positive pin current represents current flowing out of the pin. 2.0 ELECTRICAL CHARACTERISTICS Specifications apply over all line and load conditions, T = 25 C and output voltage from 20V to 55V, unless otherwise J noted. Boldface specifications apply over the temperature range of -40 C < T < 125 C (T-grade). J PRMRegulator Rev1.2 vicorpower.com Page2of22 07/2015 800927.9474
