Highly efficient high current eighth-brick DC/DC converters suit 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 × 22.86 × 9.91mm (2.3 × 0.9 × 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 48 VDC. 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°C to +85°C. Protection features include input under voltage, output short circuit, over current and over temperature.
