NNL05 Datasheet, PDF (1/9 Pages) C&D Technologies – NON-ISOLATED DC DC CONVERTERS

NNL05 SERIES
Non-Isolated DC/DC Converters
FEATURES
• ^{Industry standard footprint}
• ^{Short circuit protection}
• ^{High efficiency}
• ^{Under voltage lock out}
• ^{Fully adjustable output voltage}
• ^{Operating temperature range}
–40°C to 85°C
• ^{Fully adjustable output voltage}
• ^{SMD construction}
DESCRIPTION
The NNL05 series is part of a range
of non-isolated, cost effective DC/DC
converters offering high precision
output voltages from a nominal
3.0-5.5V or 10.0-14.0V intermediate
bus where isolation is not required.
Currently available in SMD format
and packaged in stackable trays
(optional tape and reel packaging
on request). UL60950 recognition
pending.
