Dover, NJ – August 12, 2019 – Polytron Devices, a leading designer and supplier of standard and custom DC-DC converters, switching power supplies and linear power modules, recently introduced a family of 2- and 3.5-watt DC-DC converters for medical applications. The 2:1 input range MTWA2 and MTWA4 2-watt and 3.5-watt DC-DC converters feature a low leakage current of 2 µA and offer 5000V AC input to output isolation and 2 x MOPP patient protection — the highest level according to IEC 60601-1 safety standards for electrical medical products.

The devices cover an extra-wide input range of 4.5V to 12V DC as well as 9V to 18V DC, 18V to 36V DC and 36V to 75V DC input ranges. They also offer up to 82 percent efficiency, remote ON/OFF and a high operating altitude of 5,000 meters. Safeguards include over voltage, short circuit and under voltage protection with no minimum load requirement.

Thanks to their low leakage current, availability in miniature DIP16 (0.95 x 0.57 x 0.41 inches) and SMD16 (0.95 x 0.57 x 0.40 inches) packages and process efficiencies that result in a lower cost versus previous DC-DC converters, the MTWA2 and MTWA4 are especially desirable for use in portable devices with low wattage requirements. In addition to their IEC 60601-1 Medical safety approval, the units comply to the RoHS 2011/65/EU Directive.

The MTWA2 and MTWA4 Series DC-DC converters with 2:1 input range are both available in 4:1 input versions — MTWB2 (2 watts) and MTWB4 (3.5 watts), respectively.
