8.1 Application Information

The power stage CSD97374Q4M 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.
