Recom R1SX 1W SMD Isolated DC-DC Converter
The R1SX is a low cost, 1 W, low profile, open-frame, SMD isolated DC-DC converter. It is available with 3.3 V or 5 V inputs and offers a single unregulated 3.3 V or 5 V output. There is no minimum load requirement and the quiescent consumption is less than 150 mW. Isolation is 1 k V dc or 3 k V dc and the operating temperature is -40°C up to +100°C (without derating). The pin-out is industry standard and compatible with the R1S series, but at half the height. The converter is fully certified to IEC/EN/UL62368 and 60950 and is 10/10 RoHS-conform. Class B EMC conformity can be reached with a simple external LC filter.
