Low-cost 1W DC-DC converters with dual outputs

RECOM has extended its portfolio with the R1DX series to cover dual output voltage applications. The series is perfect for EIA/TIA-232 bus isolation and a wide range of industrial automation control equipment, sensors, isolated operational amplifiers, and test and measurement equipment that need bipolar supply voltages. The series are high-quality open-frame SMD converters, which deliver stable performance on symmetric dual outputs at a very competitive price. They operate from 5V and offer ±5, ±9, ±12 or ±15 dual outputs. There is no minimum load required, and the quiescent consumption is less than 150mW. The pin-out is industry standard and compatible with the R1S/R1D series. High isolation of up to 3kVDC (/H option) makes them an ideal solution for isolating data transfer lines in legacy communication protocols (e.g. RS-232) and for isolated DAC and sensor applications. The modules operate at a wide temperature range from -40C to +95C without derating and can drive up to ±1000µF capacitive loads, which is multiple times higher than the competition. The series is fully certified to IEC/UL/EN62368-1 and UL60950-1 and is 10/10 RoHS-conform. Class A EMC conformity requires only an input capacitor, and a simple low-cost LC filter is all that is needed for Class B EMC.
