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 0.0-4.0V intermediate bus where
isolation is not required. Currently available in
SMD format and packaged in stackable trays or
tape and reel packaging. The product range has
been recognized by the Underwriters Laboratory
(UL) to UL60950, file number E79522 applies.

. If components are required in tape and reel format suffix order code with -R, e.g. NNL05-9C-R.
2. A 330µF low ESR capacitor, approx 7mΩ at 00kHz to 300kHz must be fitted at the input to the NNL DC/DC converter to ensure
stability under all the operating conditions.
