PRODUCT OVERVIEW
The NCS6 series of DC/DC converters offers
single & dual 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.

APPLICATION NOTES
Output Capacitors
The NCS6 series does not require output capacitors to meet datasheet specification. To meet datasheet specification, total output capacitance should not exceed:

Minimum Load
The minimum load to meet full datasheet specification is 10% of the full rated load across the specified input voltage range.
Between 0% and 10% output loading, the positive output voltage will remain within data sheet specification however, output ripple and noise will increase as well as a
decrease in accuracy on negative outputs.
