New 3W DC-DC converter series offers wide input ranges

RECOM has expanded its range of DC-DC converters with a 3W version of its isolated RSH series in a surface-mount format with wide input ranges.

The RECOM RSH3 DC-DC converter is an expansion to the successful RSH2 series providing fully regulated, low-noise, and isolated 3W outputs in a surface mount package. The series provides nominal inputs of 12V (9-18V) and 24V (18-36V), which are valuable for battery or bus-powered systems, while the outputs offered are 5V, 12V, 15V, 24V, +/−12V, and +/−15V. The parts have short-circuit and overcurrent protection and meet EN 55032 class A or B limits for input noise with a simple external filter. No minimum load is needed, and the on/off control is standard.

The series functions from −40C to over 80C with no derating, making the products ideal for demanding industrial, test and measurement, and transport applications.

The isolation rating is 2kVDC/60s (optionally 3kVDC/60s) with UL/IEC/EN 62368-1 certification. The parts are RoHS-2 compliant.

The series is provided in a compact, lightweight DIP14 SMD case, offered in tube or tape-and-reel packaging. The parts can be IR-oven or vapour-phase reflow soldered employing industry-standard JEDEC profiles.

Matthew Dauterive, the DC-DC product manager of RECOM, comments, “The surface mount RSH3 series builds on the success of our 2W version and provides extra power for isolated on-board DC rails in the mains and in the battery-powered equipment. The RSH3 will also find use in ground-loop isolation for industrial sensors and bus communication networks.”
