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.
