Murata Power Solutions has developed 1-Watt regulated DC-DC converters with 1kVDC or 3kVDC input to output isolation and 13 per cent higher energy efficiency compared to existing models. The Murata MEF1 series, which has applications in the industrial, automation and instrumentation industries, has been submitted for UL60950 safety standard certification.

The tightly regulated single output converters, rated to better than 1 per cent of nominal output voltage, are packaged in a single-in-line through-hole format occupying less than 1.17cm squared footprint.

The MEF1 converters are available with either 1kVDC or 3kVDC input to output isolation, the latter model having an enhanced immunity to voltage transients. Output voltage options are 3.3VDC or 5.0VDC, with input voltages covering the popular nominal inputs from 3.3VDC to 24VDC. Both the 3.3VDC input and 3.3VDC output options can operate over the full industrial temperature range of -40 to +85°C without derating.
