“The Cube” Sets New Standard For 1W Isolated DC-DC Converters

Mansfield, Mass., USA: According to Murata Power Solutions, its MTU1 dc-dc converter series marks a change in the miniaturisation of power modules, achieving new benchmarks for footprint, load regulation and efficiency. The series suits industrial, test-and-measurement, and process control applications, as well as all application segments that require an isolated surface mount dc-dc converter.

The MTU1 converters measure 8.2 x 8.4 x 8.5mm, a 50% footprint reduction compared to the previous generation. Power density is 1.71W/cm3, and temperature performance at full 1W load is between -40 and 85ºC. Load regulation has been enhanced to only 7.5%, a change of 40%.

Power dissipation drops 56% versus the MTU1’s predecessor, and running temperatures are also lower. The increase in efficiency and power-dissipation reduction enables the series' open frame design.

Eight models are available in the MTU1 series, with either 5 or 12V input voltage, and 5, 9, 12 or 15V output voltage. Each module has a single output, isolated to 1kVdc. All are RoHS-compliant.

Ann-Marie Bayliss, product manager, says that "with tri-fold improvements in footprint, efficiency and load regulation, the MTU1 truly deserves the accolade ‘innovation cubed.’”
