Murata Shrinks DC-DC Converter Size
Reduced-size DC-DC converter.
Mansfield, MA — Murata has introduced the MEU1 series of ultra miniature single isolated output 1 Watt DC-DC converters from Murata Power Solutions. Measuring just 8.30 x 6.10 x 7.55mm, this new series of converters achieves a 26 percent footprint reduction when compared to previously released products. Available for through-hole mounting with staggered style pin outs, the MEU1 achieves a 25 percent increase in power density and can deliver its output power over the whole temperature range of -40 to +85°C. The reduction in converter volume and footprint allows engineers to reduce the overall dimensions of their application, which is critical for space-constrained designs.
Conversion efficiency has also been improved by typically 6 percent across the full load range compared to previous models. Efficiency improvements contribute to lowering the overall system power consumption in addition to increasing system reliability. The MEU1 series also has load regulation that is typically 3 percent better than the industry norm when compared to similar miniature through-hole converters. This reduces the need for any additional external regulation components and further conserves precious board space.
A total of 14 models are available, with the popular input voltages of 3.3, 5, or 12VDC and providing outputs of 3.3, 5, 9, 12, or 15VDC. The unit's 1kVDC galvanic isolation aids reduction of switching noise and allows the converter to be configured to provide an isolated negative rail in systems where only positive rails exist.
