3 Description

The CSD95420RCB NexFET™ power stage is highly

optimized for high-power, high-density synchronous

buck converters. This product integrates the driver

device 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 4 mm × 5 mm outline package.

The device 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 simplifies

the completion of the overall system design.
