R1SX/R1DX

Description

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, ±9, ±12 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/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)
