1W Regulated & Isolated SMT DC-DC Converters

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 3.3V or 5V outputs from Murata Power Solutions. Inputs available are nominal 3.3V and 5V 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 3.3V and 5V.

Parts are 100% production tested to 3kVdc and have agency recognition pending for ‘basic’ protection at 250Vrms and ‘reinforced’ protection at 125Vrms to UL60950. Medical recognition to ANSI/AAMI ES 60601-1 is also pending for 2 MOOPs 1 x MOPP at 125Vrms and 1 MOOP 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 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 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 5.01mm 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 degrees C and Moisture Sensitivity Level (MSL) 2.
