Low-Cost Dual-Output 1W DC-DC Converters with 3kVdc Isolation

May 08, 2018 by Paul Shepard

Following the success of the single-output R1SX 1W dc-dc converters, RECOM has extended its portfolio with the R1DX series to cover dual-output voltage applications. The R1DX series is designed for EIA/TIA-232 bus isolation and a wide range of industrial automation control equipment, sensors, isolated operational amplifiers and test & measurement equipment that require bipolar supply voltages.

The R1DX 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) make them a 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 -40°C to +95°C 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. Samples are now available from all authorized distributors.
