Eighth-Brick DOSA-Compliant 150W DC-DC

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 +85 degrees C. 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. As low as $21.00 in OEM quantities; samples available upon request. The lead-time for production units is 12-14 weeks.
