NCP5351  
4 A Synchronous Buck  
Power MOSFET Driver  
The NCP5351 is a dual MOSFET gate driver optimized to drive the  
gates of both high−side and low−side Power MOSFETs in a  
Synchronous Buck converter. The NCP5351 is an excellent  
companion to multiphase controllers that do not have integrated gate  
drivers, such as ON Semiconductor’s CS5323, CS5305 or CS5307.  
This architecture provides a power supply designer the flexibility to  
locate the gate drivers close to the MOSFETs.  
The 4.0 A drive capability makes the NCP5351 ideal for minimizing  
switching losses in MOSFETs with large input capacitance. Optimized  
internal, adaptive nonoverlap circuitry further reduces switching  
losses by preventing simultaneous conduction of both MOSFETs.  
The floating top driver design can accommodate MOSFET drain  
voltages as high as 25 V. Both gate outputs can be driven low, and  
supply current reduced to less than 25 mA, by applying a low logic  
level to the Enable (EN) pin. An undervoltage lockout function  
ensures that both driver outputs are low when the supply voltage is  
low, and a thermal shutdown function provides the IC with  
overtemperature protection.
