The RBC-12/17-D48 regulated bus converter delivers up to 210-W output power, with a Vin range of 36 to 75 V, 92.5% efficiency at full load, and ±1.5% VOUT regulation. The quarter-brick open-frame package converter is optimized for use in distributed-power regulated intermediate bus architectures where it can be used to drive PoL converters. Applications include 48-V-powered datacom and telecom installations, base stations, cellular telephone repeaters and embedded systems.
The fully isolated 2,250-Vdc bus converter accepts inputs from 36 to 75 Vdc (48 V nominal). The inputs are converted to a 12-Vdc 17-A output. It features synchronous-rectifier topology and 225-kHz fixed-frequency operation. Protection features include input undervoltage lockout, output current limiting, short-circuit hiccup, overtemperature shutdown, and output overvoltage.
