3 Description

The CSD97396Q4M 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 is

optimized to help reduce design time and simplify the

completion of the overall system design.
