DESCRIPTION  
The CSD95373AQ5M NexFET™ Power Stage is a highly optimized design for use in a high-power, high-density  
synchronous buck converters. This product integrates the driver IC and NexFET technology to complete the  
power stage switching function. The driver IC has a built-in selectable diode emulation function that enables  
DCM operation to improve light load efficiency. This combination produces high current, high efficiency, and high  
speed switching capability in a small 5 x 6 mm outline package. It also integrates the temperature sensing  
functionality to simplify system design and improve accuracy. In addition, the PCB footprint has been optimized  
to help reduce design time and simplify the completion of the overall system design.
