3 Description
The CSD95491Q5MC NexFET™ 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 has been
optimized to help reduce design time and simplify the
completion of the overall system design.
