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

1. 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 17mΩ at 100kHz to 300kHz must be fitted at the input to the NNL DC/DC converter to ensure
stability under all the operating conditions.
All specifications typical at T =25°C, nominal input voltage and rated output current unless otherwise specified.
