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 un-regulated NMK series
has superior output voltage set point accuracy 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
