1W DC/DC Converters Power Remote Sensors

Murata’s NXF1 series 1W, surface-mount (SMT) dc/dc converters are designed for applications requiring tight output regulation. These include powering remote pressure, hall-effect, mass airflow, and other sensors and in markets that include alternative energy/solar power, transportation, telecom/wireless equipment, and medical.


Inputs available are nominal 3.3V and 5V, line regulation is typically better than 0.03%, and load regulation is typically better than 0.5%. All components in the series 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 3 kVdc and carry 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.


Additionally, operating temperature ranges from -40°C to +105°C with derating depending on model. For further information, an NXF1 series datasheet awaits your perusal.
