1-W DC/DC converter reduces footprint by 34 percent

July 03, 2015 // By Paul Buckley
The MTC1 series of 1 Watt regulated single output DC/DC converters manufactured by Murata Power Solutions has shrunk the device's footprint by 34 percent.

The miniature isolated devices are available with nominal input voltages of 12 or 24 VDC and accommodate a 2:1 input range around the selected nominal. Having such a wide input range allows for use in designs with different nominal input voltages or in situations where wide voltage deviations might occur.

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. Occupying a third less PCB area that competing parts the MTC1 can operate up to 105 degrees C with derating.
