The CSD97394Q4MT is a synchronous buck NexFET™ Power Stage with highly-optimized design for use in a high-power/-density synchronous buck converter. This product integrates the driver IC and NexFET technology to complete the power stage switching function. The driver IC has a built-in selectable diode emulation function that enables DCM operation to improve light load efficiency. In addition, the driver IC supports ULQ mode that enables connected standby for Windows® 8. With the PWM input in tri-state, quiescent current is reduced to 130µA, with immediate response. When SKIP# is held at tri-state, the current is reduced to 8µA (typically 20µs is required to resume switching). In addition, the PCB footprint is optimized to help reduce design time and simplify the completion of the overall system design.
