3 Description
The CSD97374Q4M NexFET™ power stage is a
highly optimized design for use in a high-power, highdensity
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 highspeed
switching device in a small 3.5-mm × 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.
