1 W regulated SMT DC-DC converter

18 April 2018 Power Electronics / Power Management

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 very 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 restart 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 kV d.c. 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 MOOP (means of operator protection) and 1 x MOPP (means of patient protection) at 125 Vrms 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-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, telecom/wireless equipment and medical.

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 1 W converters in the Murata proprietary iLGA inspectable format with gold plated terminations. Height is just 5,01 mm maximum including tolerances. Parts are fully compatible with lead-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.
