Murata Announces New 2W Single Output DC-DC Converter

March 04, 2008 by Jeff Shepard

Murata Power Solutions announced the NMK series of isolated 2W single output dc-dc converters, which the company claims provide industry leading performance in a small footprint, pin compatible, industry standard SIP package that allows easy drop-in replacement of other devices. The NMK series also provides a straightforward power upgrade path from the company’s existing 1W NMV series.

Comprising eight models, the un-regulated NMK series offers designers a choice of 5 and 12V inputs and output voltages of 5, 9, 12 or 15V. Efficiency of 89% typical (at 15V output), an output voltage set point accuracy of 7%, and 2.5% (for a 15V output) maximum load regulation performance combine to give the NMK series what the is said to be industry-leading performance for converters of this type.

The RoHS compliant NMK series offers 3kVdc isolation (for 1 minute) and power density of up to 1.33W/cm3. The new devices are able to maintain full 2W load performance across an industrial operating temperature range of -40 to +85°C without any external heatsinking.

According to the company, the fully encapsulated UL 94V-0 approved package has an internal construction that uses advanced toroidal magnetics, and with no external components required, integration of the NMK series into existing designs is greatly simplified.
