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.

1 Calculated using MIL-HDBK-217F with nominal input voltage at full load.
2 To order with optional control pin, prefix C with “E”. For example NDS6D0505EC.
3 Operation below 10% minimum load may cause increased output ripple.
All specifications typical at TA=25°C, nominal input voltage and rated output current unless otherwise specified.
