PRODUCT OVERVIEW
The NMK series of industrial temperature range
DC/DC converters, available in industry standard
SIP packaging offers a power upgrade path
from the 1W NMV series. The NMK offers 3kVDC
isolation with 5V output minimum efficiency of
80% at 2W. The un-regulated NMK series has
superior output voltage set point accuracy of 6%
in conjunction with excellent load regulation for
this converter type.
Unbalanced loading capabilities on dual output
variants, all of the rated output power may be
drawn from a single output.

When operated with additional external load capacitance the rise time of the input voltage will determine the maximum external
capacitance value for guaranteed start up. The slower the rise time of the input voltage the greater the maximum value of the
additional external capacitance for reliable start up.
