OUT  
The TPS4000x are controllers for low-voltage,  
10-Lead MSOP PowerPadt Package for  
non-isolated synchronous buck regulators. These  
controllers drive an N-channel MOSFET for the  
primary buck switch, and an N-channel MOSFET  
for the synchronous rectifier switch, thereby  
achieving very high-efficiency power conversion. In  
addition, the device controls the delays from main  
switch off to rectifier turn-on and from rectifier  
turn-off to main switch turn-on in such a way as to  
minimize diode losses (both conduction and  
recovery) in the synchronous rectifier with TI’s  
proprietary Predictive Gate Drivet technology. The  
reduction in these losses is significant and increases  
efficiency. For a given converter power level, smaller  
FETs can be used, or heat sinking can be reduced  
or even eliminated.
