3 Description

The CSD95373BQ5M 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 has been

optimized to help reduce design time and simplify the

completion of the overall system design.
