Description
1 Watt
SMD
Single & Dual
Output
Low cost, low profile, open-frame 1W SMD isolated DC/DC converters available with single (R1SX) or
dual (R1DX) outputs. The R1SX is available with 3.3V or 5V inputs and offers a single unregulated 3.3V
or 5V output. The R1DX operates from 5V and offers ±5, ±±, ±1ꢀ or ±15 dual outputs. There is no
minimum load requirement and the quiescent consumption is less than 150mW. Standard isolation is
1kVDC/1s and a /H version with 3kVDC/1s is available. The operating temperature is from -40°C up to
+100°C without derating. The pin-out is industry standard and compatible with the R1S/R1D series, but
at half the height. The converters are fully certified to IEC/EN/UL6ꢀ368 and IEC/EN/UL60±50 and are
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. Standard packaging is tape and reel.
