Features Unregulated Converters Description 1W Power In SMD Package Pin Compatible With R1S -4 C To +1 C Operating Temperature @ Full Load high 3kVDC/1 Second or 1kVDC/1 Second Isolation IEC/EN/UL62368-1 Certifed, CB Report The is a low cost, 1W, low profile, open-frame, SMD isolated DC/DC converter. It is available with 3.3V or 5V inputs and offers a single unregulated 3.3V or 5V output. There is no minimum load requirement and the quiescent consumption is less than 15mW. Isolation is 1kVDC or 3kVDC and the operating temperature is -4 C up to +1 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 695 and is 1/1 RoHS-conform. Class B EMC conformity can be reached with a simple external LC filter. Selection Guide Part nom.
