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 3.
FEATURES
UL 60950 recognized
RoHS compliant
Efficiency from 80%
Power density 1.31W/cm3
Wide temperature performance at full
2 Watt load, –40°C to 85°C
UL 94V-0 package material
No heatsink required
Industry standard pinout
3kVDC isolation (1 minute)
5V, 12V, 15V & 24V inputs
5V, 9V, 12V, & 15V output
Fully encapsulated with toroidal
magnetics
No electrolytic or tantalum capacitors
