Single-Phase Voltage  
Regulator  
High Efficiency, Integrated Power MOSFETs  
NCP3284, NCP3284A  
The NCP3284/A, a singlephase synchronous buck regulator,  
integrates power MOSFETs to provide a highefficiency and  
compactfootprint power management solution. The NCP3284 is able  
to deliver up to 30 A TDC output current, 35 A TDC for NCP3284A,  
over a wide input and output operating voltage range. Operating in  
high switching frequency up to 1 MHz allows employing small size  
inductors and capacitors while maintaining high efficiency due to  
integrated solution with high performance power MOSFETs. It  
provides differential voltage sense, flexible softstart programming,  
and comprehensive protections.
