validate and test their design implementation to confirm system functionality.

8.1 Application Information

The Power Stage CSD97394Q4M is a highly optimized design for synchronous buck applications using NexFET

devices with a 5 V gate drive. The Control FET and Sync FET silicon are parametrically tuned to yield the lowest

power loss and highest system efficiency. As a result, a rating method is used that is tailored towards a more

systems centric environment. The high-performance gate driver IC integrated in the package helps minimize the

parasitics and results in extremely fast switching of the power MOSFETs. System level performance curves such

as Power Loss, Safe Operating Area and normalized graphs allow engineers to predict the product performance

in the actual application.
