PRODUCT OVERVIEW
The NDS6 series of DC/DC converters offer single
and dual output voltages from an input voltage
range of 18-36V. The NDS6 is housed in an indus-
try standard package with a standard pinout. The
NDS6 is packaged in a metal case for improved
EMI shielding and is also encapsulated for supe-
rior thermal performance. Versions with optional
remote on/off control pin are also available.
Applications include telecommunications, battery
powered systems, process control and distributed
power systems.
