DESCRIPTION
The NNL05 series is part of a range of nonisolated, 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 or tape and reel packaging. The product range has been recognized by the Underwriters Laboratory (UL) to UL60950, file number E179522 applies.

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 TA =25°C, nominal input voltage and rated output current unless otherwise specified.

OUTPUT VOLTAGE ADJUSTMENT
The trimming (adjust) input on the device allows output voltage adjustment from 0.75V to 3.3Vdc (NNL05-9C) or 5.0 (NNL05-10C) by using a resistor as shown in fig.1 or by applying a voltage between trim and common pins as shown in fig.2. To calculate the resistor value for NNL05-9C: RTRIM = 21070 – 5110 Ω VOUT – 0.7525
