Murata Power Solutions' Regulated Bus Converter (RBC) delivers
up to 210W output power, with a Vin range of 36-75V, efficiency of 92.5 percent
at full load with Vout regulation (±1.5 percent) in a quarter brick open frame
design of the RBC-12/17-D48 dc/dc bus converter has been optimized for use in
distributed power Regulated Intermediate Bus Architectures (RIBAs) where it can
be used to drive point-of-load (PoL) converters. Applications include
48V-powered datacom and telecom installations, base stations, cellular
telephone repeaters and embedded systems.
fully isolated (2250V dc) RBC-12/17-D48 is able to accept a wide range 36 to
75V dc (48V nominal) input. This is then converted to a 12V dc/17A output.
Overall dimensions of 2.22 (56.39) x 1.45 inch (36.83 mm) plus a low overall
height of 0.42 inch (10.67 mm) allow the RBC to fit into applications where
card cage space is restricted.
synchronous-rectifier topology and 225kHz fixed-frequency operation of the RBC
results in the efficiency levels. The present trend in distributed power architectures
(DPAs) require Wide Vin ranges, high efficiency and Vout regulation for the
most efficient regulated IBA systems.
features incorporated in this product are input under-voltage (UV) lockout,
output current limiting, short-circuit hiccup, over-temperature shutdown and
output over-voltage. Positive or negative polarity remote on/off control is
available as an option. A base plate, for mounting to cold surfaces or
natural-convection heatsinks, can be specified for applications that do not have
forced air cooling or where there is zero airflow. The RBC-12/17-D48 possesses
all relevant FCC, UL and IEC certifications for emissions, safety and

In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
