1W DC/DC Powers Remote Sensors


Murata has announced new 1W, surface-mount (SMT) dc/dc converter designed for applications requiring tight output regulation. These include systems providing power for remote pressure, hall-effect, mass airflow and other sensors in alternative energy/solar power, transportation, telecom/wireless equipment and medical applications.

The new NXF1 series 1W DC/DC converter is a cost-effective, fully regulated, high isolation converter with 3.3 V or 5 V outputs.

Inputs available are nominal 3.3 V and 5 V, line regulation is typically better than 0.03 % and load regulation typically better than 0.5 %.


All parts have continuous short circuit protection with auto re-start or latch-off depending on model and temperature. Input range is +/-5 % around the nominals of 3.3 V and 5 V.

Parts are 100% production tested to 3kVDC and have agency recognition pending for ‘basic’ protection at 250 Vrms and ‘reinforced’ protection at 125 Vrms to UL60950.

Medical recognition to ANSI/AAMI ES 60601-1 is also pending for 2 MOOPs (Means Of Operator Protection) and 1 x MOPP (Means Of Patient Protection) at 125 Vrms and 1 MOOP (Means Of Operator Protection) based upon a working voltage of 250 Vrms max, between Primary and Secondary.

“The NXF1 series is an exciting new product which builds on our unique embedded magnetic core technology giving our customers great electrical and isolation performance with hassle-free placement at a competitive price” said Ann-Marie Bayliss, Product Manager, Murata Power Solutions

The NXF1 series is rated at -40° to +105° C with derating depending on model.
