3 Description  
The CSD95378BQ5MC NexFET™ smart power  
stage is a highly-optimized design for use in a high-  
power, high-density synchronous buck converter.  
This product integrates the driver IC and power  
MOSFETs to complete the power stage switching  
function. This combination produces high-current,  
high-efficiency, and high-speed switching capability in  
a small 5 mm × 6 mm outline package. It also  
integrates the accurate current sensing and  
temperature sensing functionality to simplify system  
design and improve accuracy. In addition, the PCB  
footprint is optimized to help reduce design time and  
simplify the completion of the overall system design.
