Murata Releases High Current Eighth-Brick DC-DC Converters for High Density Embedded Applications

Murata Power Solutions announced the introduction of the UWE series of highly efficient 100 – 120 Watt open frame isolated DOSA-compatible eighth-brick dc-dc converters. Using the industry standard through-hole package, measuring 58.42 x 22.86 x 9.91mm (2.3 x 0.9 x 0.39 inches), the single output units offer the nominal outputs of 3.3, 5 or 12Vdc. Providing an efficiency of typically 91.5 % means that for most applications no forced airflow is required.

Suiting embedded computing applications and instrumentation subsystems, the converters accommodate an ultra-wide 4:1 input voltage range from 18 to 75Vdc around a nominal 48Vdc. Line regulation is kept within ± 0.25% Vout and load regulation is maximum ±0.2% Vout across the complete range. On-board remote sense inputs compensate for line voltage errors at high output currents. A trim function provides the ability to adjust outputs +/- 10% of nominal output voltage in order to compensate for line losses.

A remote on/off input, negative or positive, provides the ability to remotely control the converter such as required to schedule load startup. The UWE series can operate from –40 to +85°C. Input to output isolation is 2,250Vdc. Protection features include input under voltage, output short circuit, over current and over temperature. An optional baseplate is available for conduction cooled applications.
