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 this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
Microchip recently released the 3D TouchPad, the first USB PC Peripheral device that couples 2D multi-touch input with 3D air gesture technology. The company seeks the help of developers to further enhance the capabilities of the technology.
To give engineers a better idea of the range of resins and polymers available as alternatives to other materials, this Technology Roundup presents several articles on engineering plastics that can do the job.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
