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.
