3 Description

The CSD96416 NexFET™ power stage is a highly

optimized design for use in a high-power, high-density

synchronous buck converter. This product integrates

the driver 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 package.

This power stage has an adjusted deadtime trim

to improve transient response with non-TI controller.

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.
