RECOM R1SX series 1 W DC/DC converters

RECOM’s R1SX series has a nearly 20% lower profile than the industry standard due to its inverted transformer design, the company says. The 1 W DC/DC converters are suitable for bus isolation and a wide range of industrial automation control equipment.

The R1SX series, an open-frame SMD converter, leverages fully automated manufacturing techniques to deliver stable performance and consistent high quality. The modules are available with 3.3 or 5 V inputs, offer a single unregulated 3.3 or 5 V output and can reach up to 78% efficiency. There is no minimum load required and the quiescent consumption is less than 150 mW.

RECOM says the converters can drive up to 2200 µF of high capacitive load, which is 40 times higher than the competition. With up to 3 kVDC (/H option) of isolation, it makes them suitable for isolating data transfer lines in industrial communication protocols (eg, CAN bus). The modules operate at a wide temperature range from -40 to +100°C at full load and have industry standard pinouts that are compatible with the R1S series but at half of its height.

Class A EMC compliance can be reached without external inductors, and Class B EMC compliance can be met with one additional inductor. The series is fully certified to IEC/UL/EN62368-1 and UL60950-1.
