FEATURES
DESCRIPTION
The NKA sub-miniature series of industrial
temperature range DC/DC converters are the
standard building blocks for on-board distributed
power systems. The series offers smaller package
size, improved effi ciency, lower output ripple and
3kVDC isolation capability through the use of state
of the art packaging and technology. Ideally suited
for providing dual rail supplies on primarily digital
boards with the added benefi t of galvanic isolation
to reduce switching noise.
All of the rated power may be drawn from a single
pin provided the total load does not exceed 1 watt.
www.murata-ps.com
RoHS compliant
Effi ciency up to 82%
Wide temperature performance at full
1 Watt load, –40°C to 85°C
UL 94V-0 package material
Reduced footprint at 0.98cm
Industry standard pinout
Power sharing on output
3.3V, 5V & 12V Input
3.3V, 5V, 9V, 12V and 15V output
Internal SMD construction
Fully encapsulated with toroidal magnetics
No external components required
MTTF up to 1.6 Million hours
No electrolytic or tantalum capacitors
