NCP5211  
Low Voltage Synchronous  
Buck Controller  
The NCP5211 is a low voltage synchronous buck controller. It  
contains all required circuitry for a synchronous buck converter using  
external N−Channel MOSFETs. High current internal gate drivers are

MARKING  
capable of driving high gate capacitance of low R  
NFETs for  
DS(on)  
better efficiency. The NCP5211 is in a 14−pin package to allow the  
designer added flexibility.  
DIAGRAM  
The NCP5211 provides overcurrent protection, undervoltage  
lockout, Soft−Start and built in adaptive nonoverlap. The NCP5211  
also provides adjustable fixed frequency range of 150 kHz to 750 kHz.  
This gives the designer more flexibility to make efficiency and  
component size compromises. The NCP5211 will operate over a 4.5 V  
to 14 V range using either single or dual input voltage.
