MTC1 1W DC/DC converters with wide input range from Murata

Murata MTC1

Electronics Weekly

Murata has launched the MTC1 series of 1 W regulated single output DC/DC converters with nominal input voltages of 12 or 24 VDC and accommodate a 2:1 input range around the selected nominal which allows for use in designs with different nominal input voltages or in situations where wide voltage deviations might occur.

Murata - MTC1

It is aimed at applications such as medical, industrial, telecommunications, battery powered systems, and process automation.

The range comprises six single output models providing 3.3, 5 or 12 VDC for both the 12 and 24 VDC nominal inputs. No additional regulation components are required since the MTC1 output is fully regulated to within +/- 0.5% of stated output.

A voltage trim pin allows adjustment of the output voltage by ±10% to suit any special voltage requirements. A remote on/off pin provides the ability to disable the output for application power saving.

Input to output isolation conforms to the international safety insulation standard UL60950 (Pending). With its certification to the medical safety standard ANSI/AAMI ES60601-1 for 2 MOOPs the converter is suitable for use in a wide range of medical and healthcare applications. The MTC1 can operate up to 105 degrees C with derating.
