R1SX/R1DX 1W SMD DC/DC Converters

RECOM R1SX/R1DX 1W SMD DC/DC Converters are low-profile, open-frame SMD isolated DC/DC converters available with 3.3V or 5V inputs that offer a single unregulated 3.3V or 5V output. These cost-effective converters are available with single (R1SX) or dual (R1DX) outputs. There is no minimum load requirement, and the quiescent consumption is less than 150mW. Other features of this RECOM series include 1kVDC or 3kVDC isolation and a -40°C to +100°C operating temperature (without derating). The industry-standard pinout is compatible with the R1S/R1D series but is half the height. The converters are fully certified to IEC/EN/UL62368 and 60950 and 10/10 RoHS compliant. Class A EMC conformity requires only an input capacitor and Class B EMC conformity can be reached with a simple external LC filter.
