3 Description
The CSD96497 NexFET™ power stage is a highly
optimized design for use in a high-power, highdensity
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 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.
