PRODUCT OVERVIEW
The NCS6 series of DC/DC converters offers
single output voltages from input voltage ranges
of 9-36V and 18-75V. The NCS6 is housed in
an industry standard package with a standard
pinout. The NCS6 is packaged in a metal case for
improved EMI shielding and is also encapsulated
for superior thermal performance.
Applications include telecommunications, battery
powered systems, process control and distributed
power systems.
