Miniature DC/DC converter has 2 x MOOP compliance
Available with either a 12 or 24V DC 2:1 input voltage range and output voltages of 3.3, 5.0, or 12V DC, Murata’s surface mount MTC2 has a 3kV AC input to output isolation.
The 2W single output, regulated and isolated DC/DC converters measure 14.99 x 14.22 x 11.23mm (0.59 x 0.56 x 0.44inch) and 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. An output voltage trim function permits adjustment of the output by ±10% to suit special applications. No additional regulation components are required, says the company. The 2:1 input range accommodates 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 protects both the load and the device. No electrolytic capacitors are used.
Capable of operating at full output from -40 to +85 degree C, the converter can operate up to +105 degree C with derating.
