Description

The CSD95411 NexFET™ power stage is a highly optimized design for use with a high-power, high-density synchronous buck converter. This device 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. The power stage also integrates the accurate current sensing and temperature sensing functionality to simplify system design and improve accuracy. The optimized PCB footprint helps reduce design time and simplify the completion of the overall system design.
