PRODUCT OVERVIEW
3
TBD
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.
