Vicor Corporation Power Supplies - Board Mount - DC DC Converters PRM48AT480T400A00

The 1340706-PRM48AT480T400A00 is a non-isolated ZVS buck-boost DC-DC converter designed for high efficiency and power density applications. It operates with an input voltage range of 36.0V to 75.0V and provides an adjustable output voltage from 20.0V to 55.0V, with a nominal output of 48.0V at a maximum output current of 8.33A, delivering up to 400W of power. The converter achieves a typical efficiency of 97.5% at full load and has a power density of 1383W/in², making it suitable for space-constrained applications. The device features a Full VI Chip® package, measuring 32.5mm x 22.0mm x 6.73mm, which is compatible with standard pick-and-place assembly processes. It offers two selectable operating modes: Adaptive Loop Operation for precise regulation without remote sensing, and Remote Sense Operation for external control loop applications. With a mean time between failures (MTBF) of 4.01 million hours, this converter is reliable for use in high-density power supply systems, telecommunications, and communications equipment.
