3 Description
The CSD95372BQ5MC 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.
