News Release
Isolated 2W single output DC/DC Converter sets new standards in
efficiency and load regulation
• 89% typical efficiency (15V output), 7% output voltage set point accuracy
• Maximum load regulation 2.5% (15V output)
• Wide choice of input and output voltages
• 3kVDC isolation and power density to 1.33W/cm3
• Full 2W load performance across industrial temperature range
The NMK series of isolated 2W single output DC/DC converters from Murata
Power Solutions provides 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 Murata Power Solutions’ existing 1W NMV series.
Comprising eight models, the un-regulated NMK series offers designers a
choice of 5V and 12V inputs and output voltages of 5V, 9V, 12V 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 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 40ºC to +85ºC without any external heatsinking.
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.
