The NCP1345 also features a precise, primary side based output  
current limiting circuit to ensure a constant output current limit  
regardless of programmed output voltage, or nameplate output power.

reduce switching losses. As the load decreases further, the NCP1345  
enters skip mode to manage the power delivery.  
To help ensure converter ruggedness, the NCP1345 implements  
several key protective features such as internal brownout detection, a  
maximum output current limit regardless of input voltage, a latched  
over voltage and NTC−ready overtemperature protection through a  
dedicated pin, and line removal detection to safely discharge the X2  
capacitors when the line is removed.
