Murata Eighth Brick DOSA Compliant 150 W DC-DC Converter Suits Distributed Power Applications

Press release date: February 26, 2014

Murata today announced the UEE series of 150 Watt isolated DC-DC converters from Murata Power Solutions designed for intermediate bus and distributed power architectures. Packaged in an industry standard eighth brick format, these DOSA compliant converters measure just 58.4 x 22.9 x 10.7 mm and are available with either mounting pins or as a surface mount device.

Accommodating a standard 2:1 input voltage range around a 48 VDC nominal, the UEE series comprises three models offering the popular output voltages of 3.3, 5, or 12 VDC. These high efficiency converters, typically up to 92%, have a tight line regulation of 0.1% and load regulation of up to 0.25%. Basic input/output isolation is rated at 2250 VDC and complies with safety standard EN/UL/EC 60950.

The converters are able to deliver the full output power over the industrial equipment temperature range of -40 to +85C. Safety features of the series include input undervoltage, output overcurrent, short circuit and overtemperature,

A remote On/Off control input provides the ability to sequence the startup or shutdown of the converter from another application. Also, a remote sense input allows correction of the output voltage in order to make up for line losses, and a trim function provides a user adjustment of the output.

Product Features
• 36 to 75 Vdc input range (48V nominal)
• Outstanding thermal performance and derating
• Industry standard DOSA eighth-brick pinout and package and surface mount (SMT) option
• On/Off control, trim, and sense functions
• Fully isolated, 2250 Vdc (BASIC) insulation
