Murata announced the MTC2 series of 2 Watt single output, regulated and isolated DC/DC converters from Murata Power Solutions. Available with either a 12 or 24 VDC 2:1 input voltage range and output voltages of 3.3, 5, or 12 VDC, the surface mount MTC2 has a 3 kVAC input to output isolation.

Measuring just 0.59 x 0.56 x 0.44″ (14.99 x 14.22 x 11.23mm), the converter complies with both the UL/EN 60950 reinforced insulation safety standard for use in commercial equipment and the ANSI/AAMI ES60601-1 medical safety specification with 2 x MOOP (Means of Operator Protection).

The output is regulated to ±0.5% of the nominal output voltage and an output voltage trim function permits adjustment of the output by ±10% to suit the needs of special applications. No additional regulation components are required and, with the 2:1 input range, the MTC2 is capable of accommodating applications where there may be wide deviations of the input voltage.

A remote on/off pin is available to aid sequencing power start-up in a design or to enable application power saving features. A continuous short circuit protection function ensures that both the load and the device are protected from short circuit conditions.

Capable of operating at full output from -40 to +85 °C, the MTC2 can operate up to +105 °C with derating. No electrolytic capacitors are used in the design of the MTC2.
