The NCSꢀ series of DC/DC converters offers
single & dual output voltages from input voltage
ranges of 9-3ꢀV and 18-7±V. The NCSꢀ is housed
in an industry standard package with a standard
pinout. The NCSꢀ is packaged in a metal case for
improved EMI shielding and is also encapsulated
for superior thermal performance.
