Single Output
Description
Low cost, low profile, open-frame 1W SMD isolated DC/DC single output converters. The R1SX is avail-
able 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 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/UL62368 and IEC/EN/UL60950 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.
Notes:
Note1: Efficiency is tested at nominal input and full load at +25°C ambient
Note2: Max cap load is tested at nominal input and full resistive load
Notes:
Note3: Without suffix, standard isolation voltage (1kVDC/1 second),
with suffix „/H“, high isolation voltage (3kVDC/1 second)
