Expanding its range of embedded-core DC/DC converters, Murata Power Solutions adds the NXF1 series of regulated, high isolation converter with 3.3 or 5.0V outputs. Inputs available are nominal 3.3 and 5.0V in an industry-standard, surface-mount package with a low profile of 5.1mm. Line regulation is typically better than 0.03 per cent and load regulation is typically better than 0.5 per cent. All parts have continuous short circuit protection with auto re-start or latch-off depending on model and temperature. Input range is ± five per cent around the nominals of 3.3 and 5.0V.
Parts are 100 per cent production tested to 3.0kV DC and have agency recognition pending for ‘basic’ protection at 250V rms and ‘reinforced’ protection at 125V rms to UL60950. Medical recognition to ANSI/AAMI ES 60601-1 is also pending for two MOOPs (means of operator protection) and one MOPP (means of patient protection) at 125V rms and one MOOP based upon a working voltage of 250V rms max, between primary and secondary.
Typical applications are in systems where agency-recognised isolation is required with tight output regulation as is needed in power for remote pressure, hall-effect, mass airflow and other sensors. Markets addressed include alternative energy/solar power, transportation, telecomms/wireless equipment and medical.
The NXF1 series is rated at -40 to +105 degrees C with derating depending on model.
Packaging is the industry-standard footprint for SMT 1W converters in the Murata proprietary iLGA inspectable format with gold plated terminations. Parts are compatible with Pb-free soldering and backwards-compatible with Sn/Pb systems. They can be mounted in accordance with J-STD-020 with a classification temperature of 260 degrees C and Moisture Sensitivity Level (MSL) 2.
