Latest 400 W quarter brick DC-DC converter from Murata targets telecom applications

Murata Power Solutions has announced the RBQ series of isolated 12Vout, 400 Watt DC-DC converters. The RBQ-12/33-D48 model provides what are believed to be the industry’s highest efficiencies of up to 96% from a standard DOSA-compliant quarter-brick package. The RBQ-12/33-D48 is designed to operate in most applications with convection cooling.

The RBQ-12/33-D48 can operate from a standard telephone network voltage (TNV) network supply of 36 to 75 VDC around a nominal 48 VDC. The RBQ series is ideal for use in a host of telecommunications, enterprise IT and wireless networking infrastructures that use a distributed power or regulated intermediate bus architecture. The RBQ-12/33-D48 will reliably deliver 33A/400W @ 60°C with 200LFM airflow.

Optional features include a load sharing option for higher power or N+1 applications, conformal coating for harsh environments, Positive & Negative on/off control logic and optional pin lengths to accommodate various application board thicknesses.

Protection features include output over voltage, over current protection, input under voltage and over temperature shutdown. Input / Output isolation is provided by 2,250 VDC Basic insulation.
