DESCRIPTION

The CSD97374Q4M NexFET™ Power Stage is a highly optimized design for use in a high power, high 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 130 µA,

with immediate response. When SKIP# is held at tri-state, the current is reduced to 8 µA (typically 20 µs is

required to resume switching). This combination produces a high current, high efficiency, and high speed

switching device in a small 3.5 × 4.5-mm outline package. In addition, the PCB footprint has been optimized to

help reduce design time and simplify the completion of the overall system design.
