120W Eighth-Brick DC-DC Converters for Railway and Industrial Systems

The IRE-Q12 Series of isolated dc-dc converters from Murata feature a single 120W isolated output, from an input voltage range of 9- to 36-Vdc in a fully enclosed package with industry standard eighth-brick package and footprint. Two base plate options are available, one for minimal board space consumption, the other flanged, slotted for mechanical fixing to a heatsink surface. Positive or Negative Logic On/Off control is also available.

The IRE-Q12 Series is designed for applications in the railway, industrial and transportation systems, designed to accept input from 12V or 24V nominal battery voltages. The IRE output can be trimmed +/-10% while delivering fast settling times to transient step loads and demonstrates no adverse effects from higher capacitive loads.

The IRE incorporates all relevant self-protection features including under-voltage lockout, current limit, short circuit protection and over temperature shutdown.
