UEI Series DC/DC Converters

Murata's UEI series isolated DC/DC converter family offers efficiently regulated DC power for PCB mounting

UEI Series DC/DC ConvertersMurata Power Solutions' UEI15, UEI25, UEI30 and UEI series isolated wide input range DC/DC converters offer a wealth of self-protection features that help to avoid both converter and external circuit problems. These include input undervoltage lockout, input overvoltage, and overtemperature shutdown. The outputs current limit using the "hiccup" autorestart technique and the outputs may be short-circuited indefinitely. Additional features include output overvoltage and reverse conduction elimination. The high efficiency offers minimal heat buildup and "no fan" operation.


  • Industry standard open frame packages and pinouts
  • High efficiency synchronous rectifier forward topology
  • -40 to +85°C temperature range with derating
  • Wide range input voltages 9-36 and 18-75 VDC (36-75 VDC UEI25 series)
  • Certified to UL60950-1, CSA-C22.2 No. 234, EN60950-1, 2nd Edition safety approvals
  • Extensive self-protection shut down features
  • Stable no-load operation with no required external components
  • Assembly and attachment for RoHS standards
  • Small footprint DC/DC converter, ideal for high current applications
  • Isolation up to 2250 VDC (basic)
