DESCRIPTION  
NNL05-10C  
VIN = 5.5V VOUT = 0.75V  
VIN = 5.5V VOUT = 3.3V  
VIN = 12.0V VOUT = 0.75V  
VIN = 12.0V VOUT = 5.0V  
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 or  
tape and reel packaging. The product range has  
been recognized by the Underwriters Laboratory  
(UL) to UL60950, file number E179522 applies.

Current limit inception  
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.
