Murata Power Solutions IRS-Q12 series compact DC-DC converters

Murata Power Solutions has launched the IRS-Q12 series, its latest encapsulated 1/16th brick DC-DC converter. The board mount power module incorporates advanced assembly techniques, 2250VDC isolation with a basic insulation system, and an industry leading efficiency. Additionally, the high reliability, safety features, and optional packaging configurations offer an unmatched level of performance in harsh environmental conditions.

The 50W IRS-Q12 has an input voltage range of 9VDC to 36Vdc, expanding on the 18VDC to 75VDC that the previously released IRS-Q48 series offers. This line includes module variations of 3.3VDC, 5VDC, 12VDC, 15VDC, and 24VDC with up to 50W of output power. Further, the Vin range of 9VDC to 36VDC meets the requirements of EN50155 for nominal Vin of 24VDC/28VDC, including brown out and transient conditions, in addition to serving industrial applications with a nominal 12Vin. 

The series is available with a standard or flanged baseplate to allow for various conduction cooling configurations. Other notable features include ON/OFF control with positive or negative logic, short circuit protection, as well as over-voltage and over-temperature protection. The IRS-Q12 topology also supports a pre-biased output at start-up to eliminate reverse currents that can potentially damage critical circuitry. These benefits make it ideally suited for demanding railway, industrial, lighting, smart grid, and other harsh environment applications with system bus voltages between 9VDC and 36VDC.
