Eighth-brick DC-DC converters

21 August 2013 Power Electronics / Power Management

Murata has rolled out the UWE series of 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 9,91 mm, the single-output units offer nominal outputs of 3,3 V, 5 V or 12 V d.c.

Providing an efficiency of typically 91,5% means that for most applications no forced airflow is required; an optional baseplate is available for conduction cooled applications. Suiting embedded computing applications and instrumentation subsystems, the converters accommodate an ultra-wide 4:1 input voltage range from 18 to 75 V d.c. around a nominal 48 V d.c.

Line regulation is kept within ±0,25% Vout and load regulation is maximum ±0,2% Vout across the complete range. Onboard remote sense inputs compensate for line voltage errors at high output currents and a trim function provides the ability to adjust outputs within ±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 and features input to output isolation of 2250 V d.c. Protection features include input under-voltage, output short circuit, over-current and over-temperature.
