3 Description

The CSD95410 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.
