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
