3 Description

The CSD95490Q5MC 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 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.
