Miniature medical-grade surface-mount 2W DC-DC converter

Murata Power Solutions has introduced the MTC2 series of 2W single output, regulated and isolated DC-DC converters. Available with either a 12V or 24VDC 2:1 input voltage range and output voltages of 3.3V, 5V, or 12VDC, the surface-mount MTC2 has a 3 kVAC input to output isolation. Measuring just 14.99mm x 14.22mm 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 -40C to +85C, the MTC2 can operate up to +105C with derating, says the company.
