Murata has expanded its product range of embedded-core technology DC-DC converters with the NXF1 series, a cost effective, fully regulated, high isolation converter with 3.3 V or 5 V outputs from Murata Power Solutions. Inputs available are nominal 3.3 V and 5 V in an industry-standard surface-mount package with a uniquely low profile. 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 3 kVDC 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.
Typical applications for these converters are in systems where agency-recognized 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, telecom/wireless equipment and medical.
The NXF1 series is rated at -40°C to +105°C with derating depending on model and provides high reliability with its patented embedded-core technology which makes production fully automatic yielding a cost-effective product with excellent performance repeatability.
Packaging is the industry-standard footprint for SMT 1W converters in the Murata proprietary iLGA inspectable format with gold plated terminations. Height is an industry-leading 5.01 mm maximum including tolerances. Parts are fully compatible with Pb-free soldering and are backwards-compatible with Sn/Pb systems and can be mounted in accordance with J-STD-020 with a classification temperature of 260°C and Moisture Sensitivity Level (MSL) 2.
